- North Up(default): The map is displayed North up according to the standard of Nautical Charts.
- Compass Heading Up: The map will change orientation according to the compass heading. If no compass is detected, the Course over ground will be used instead.
- COG Up: The map will change orientation according to the Course over ground.
- Manual Orientation : The user can choose the desired orientation using the input field provided. In other modes, this field is grayed out and filled in with the effective value of the orientation

- Angle tolerance: This parameter is used to define a tolerance for the "Heading Up" or "COG Up" modes, in order to prevent the map from moving constantly. With a value of 15°, the orientation will only be adjusted if the heading/course angle deviates more than 15° from the current orientation of the map.
- Inland ENCs options: This option is dedicated to Inland Navigation, and more particularly to Inland ENCs. It allows you to filter the type of panels displayed depending on whether the boat is navigating on the river toward Upstream or towards Downstream.
From version 21.0, it is possible to start listening to the GPS and other Instruments automatically when launching ScanNav.
The settings are made in the "Navigation" tab of preferences.
- Check "Input instruments" to automatically start the GPS as well as all the other instruments declared in the "Instruments" tab
- Check "Output instruments" to automatically start the Nmea transmission on the ports declared in the "NMEA outputs" tab
To avoid confusion about Navigation and Workshop modes, when ScanNav starts up, if you were in Workshop mode during the previous session, a confirmation request is displayed to ask for the desired mode. (Before version 21.0, ScanNav started in the last mode used)
NMEA 2000 Input
The native NMEA 2000 protocol is supported as input since version 15.0, via the Actisense NGT1 adapter.
Support for Digital Yacht iKonvert or NavLink2 adapters was added in version 21.0, and MiniPlex adapters in version 22.0.
To configure the connection, you must first configure your adapter using the tool supplied with it, especially to select the various PGN filters for reception and transmission, the characteristics and speed of the communication port, etc... Please refer to the adapter documentation.
Then, in ScanNav, go to the preferences, "GPS" tab (or "Instruments" if it is a secondary connection), and choose the "NMEA 2000" model (or protocol) corresponding to your adapter in the proposed list, as well as the corresponding COM or network port.
The speed parameters are initialized with the default values according to the adapter (115200 for Actisense and MiniPlex, and 230400 for Digital-Yacht). You should however check that it corresponds to the speed configured on the adapter itself.
Apart from exceptional cases, the other parameters must remain at their default value. Note that these parameters are not accessible for Actisense.
You can use NMEA 183 and 2000 instruments together by configuring multiple instruments on different ports. Note that the Digital-Yacht and MiniPlex adapters communicate NMEA 2000 data by encapsulating the data in a specific 183 sentence (!PDGY for Digital-Yacht, and $MXPGN for MiniPlex), and can also send other Nmea 183 data to the same channel. The 2 protocols will be recognized automatically by ScanNav.
Please refer to the adapter documentation for the different configuration possibilities.
The list of "PGN" (NMEA 2000 packets) interpreted by ScanNav are the following:
General PGNs:
- 126992: System Time
- 129029: GNSS Position Data (deactivates PGN 129025)
- 129025: Position, Rapid Update (only active if PGN 129029 is not detected)
- 129026: COG & SOG, Rapid Update
- 127250: Vessel Heading
- 128259: Speed
- 128267: Water Depth
- 130306: Wind Data
- 130577: Direction Data
- 129038: AIS Class A Position Report
- 129039: AIS Class B Position Report
- 129040: AIS Class B Extended Position Report
- 129794: AIS Class A Static and Voyage Related Data
- 129041: AIS AtoNs (Aids to Navigation) support.
- 129809: AIS Class B static data (msg 24 Part A)
- 129810: AIS Class B static data (msg 24 Part B)
- 130842: Simnet: AIS Class B static data (msg 24 Part A) (variant of 129809, ignored if PGN 129809 is present)
- 130842: Simnet: AIS Class B static data (msg 24 Part B) (variant of 129810, ignored if PGN 129810 is present)
- 129793: AIS UTC and Date Report (Base Station Report, msg 4 + 11)
From version 21.0 any PGN can be interfaced as a Sensor using a configuration file. A list of PGNs (130310 to 130316 corresponding to the environmental sensors - Temperatures, Pressure, Humidity) is configured by default in 22.0, and PGNs 127488 (Engine Parameters, Rapid Update) and 128275 (Distance Log)were added inversion 22.1. It is possible to set up additional ones by editing the configuration file, but as this is a relatively technical subject, we recommend that you call in a technician for the implementation. We will provide technical information on request and according to the PGNs to be taken into account.
Refer to the documentation "Repeaters configuration" for more details on taking into account as repeaters and / or logging in the track for analysis.
Note: the General and AIS PGNs listed above perform specific functions in ScanNav and it is not necessary to configure them.
It is also possible to filter PGNs and / or transmitting sources, in order to overcome the redundancy of contradictory data on the Nmea bus (for example several GPS connected on the same bus). Go to the "Configuration" dialog of "Misc. Sensors", or the "Navigation" tab of the Preferences, and click on the "N2K PGN Filters" button. A window will offer you 2 fields:
- PGN / Sources to block: These are the PGNs and / or sources to block
- Authorized PGNs: If this list is filled in, only the listed PGNs will be taken in account
- If this value is entered in the "to block" field, all PGNs coming from source 25 will be blocked, as well as PGN 130312 whatever the source, and source 32 from PGN 130311
- Conversely, if this value is entered in the "authorized" field, only the PGNs / sources corresponding to these criteria will be taken into account.
NMEA 2000 output
Until version 21.1, NMEA 2000 was only supported in reception. The interface of the Pilot and other repeaters therefore always had to be in NMEA183.
Version 22.0 brings the possibility of transmitting on the NMEA 2000 bus, using Digital-Yacht and MiniPlex adapters compatible with Nmea 2000. A few adjustments were added in version 22.1. The Actisense NGT1 adapter will be supported in a future version, and others will follow.
The configuration of the Nmea 2000 outputs is carried out in the "Nmea outputs" tab of the preferences. Choose the NMEA 2000 protocol according to the model of your adapter (DigitalYacht or Miniplex), which will bring up a choice of PGNs to send. To date (version 22.0), the list of PGNs supported for output is the following (It will be completed as and when in future versions).
- PGN 126992: System Time
- PGN 129025: Position, Rapid Update
- PGN 129026: COG & SOG, Rapid Update
- PGN 129283: Cross Track Error
- PGN 129284: Navigation Data
- Choose the "SID" which indicates the source nmea2000 (Hexa-decimal field between 00 and FF)
- Check the desired PGNs entries under NMEA 2000. By default, all the supported PGNs are present and unchecked, with priority 7 and a destination address FF (broadcast)
- To change a destination or priority, click on the field, and change the value.
- The destination is a 2 Hexa-decimal digits value from 00 to FF, and the priority from 0 (higher priority) to 7 (lower priority)
- Changing the destination creates a new line with the PGN and new destination. It is thus possible to send a PGN to one or more instruments, without using broadcast
- Changing the priority does not create a new entry (it would not make sense to send the same PGN twice to the same destination with different priorities)
- Note: Depending on the adapters, you can also send a mix of nmea 183 and nmea 2000
To configure outputs, use the "NMEA outputs" tab of the preferences. It will allow you to create multiple outputs. Until version 21.1, outputs were only supported in NMEA 183. Version 22.0 provides support for NMEA 2000 as output. See previous chapter for more details.
On first launch, no output will be configured. Use the "New output" button and give the instrument a name.
Choose the NMEA 183 or 2000 protocol according to the desired output, and configure the port and speed fields according to the type of connection.
If the output port is identical to an instrument configured as input (for example a multiplexer), enter the same name (GPS if it is configured on the GPS tab), and the same port parameters (unless the multiplexer is listening on another port)
Then configure the sentences and/or PGN numbers to send to the pilot or to the external repeaters (refer to the documentation of the pilot/repeater to find out the sentences supported by it)
Notes:- To activate the effective output you must use the
button from the toolbar
- No navigation information will be sent to the pilot until navigation control (
) and GPS monitoring are active.
Starting from Version 14.1 ScanNav
can interface any instruments supporting NMEA over Wifi (or any other
IP network), using TCP or UDP protocols depending on the capabilities
of the instruments.
The parameters are set by adding a virtual port in ScanNav preferences:
Open the GPS (or Instruments, or NMEA output) tab in the preferences, and
click on the button "++" next to the port choice.
In the new window, select the desired interface from the dropdown list,
which can be:
- COM port: classic wired NMEA.
- UDP (Broadcast): listens (or sends) frames on a port number, which can be supplied (or read) by any external source(s).
- UDP (target IP): same, but allows filtering issuers by allowing only known IP. There may still be several sources, but all from the same IP.
- TCP/IP: TCP mode which is a point to point connection with only one source or destination, known by its IP address and port number used.
When you have the choice, and in the absence of recommendations , the easiest might be UDP, which allows to receive and/or send information from/to multiple instruments with only one connection.
TCP/IP enables secure connections and also lets you connect to instruments via Internet, such as AIS frames providers on the Internet. For example, you can test with port number 9009 port and IP address 67.164.75.139 which broadcasts AIS frames in the region of San Francisco. (IP address subject to change, to check the correct address, type "ping hd-sf.com" in a Windows Command Prompt)
The Device Name is determined automatically based on entered parameters. Once added, the port is stored under this name in the list of available ports, directly from the preferences window.
Internal GPS found on Windows 8.1 tablets, do not support the NMEA standards. They require a specific interface implemented in ScanNav starting with version 15.2. To set up your internal GPS, you just need to choose the "Internal GPS Sensor" model in the "GPS" tab of the preferences. All other communication parameters are useless and will be grayed out.
Other changes valid for all types of GPS:
The background color of the GPS button changes depending on the status of the GPS, so as to better draw attention in case of failure (was previously only materialized with the little smiley at the bottom right of the screen):
- When listening is not activated: background color identical to the other buttons
- When listening is activated its background color will be:
- Green if everything is functional
- Red if there is no communication with the GPS
- Yellow if the GPS communicates, but doesn't send any valid position.
Settings are done in the preferences tabs "GPS", "Instruments", or "NMEA output", under the "Nmea Log" chapter. Here you have the choice of the logging level, that can either be "None" (default option), "In a File", "In a Window", or "In a File and a Window"
- Logging
in a window is mostly useful as a help to configuration, or to check
information coming from a port in real time. When this option is used,
all Nmea sentences received on the corresponding port will be displayed
in a window as soon as you activate the instruments. If you close this
window using the red cross at the top right of the window, it will
re-display as soon as it receives new data on the port. If you close it
using the "Close" button, the window will not reappear until you
reactivate the instruments. The number of lines in the log window is
limited to a maximum of 6000, after which older lines are suppressed.
- Logging to a file will save all received information in a file. This can be very useful in case you contact us for a support action to help detecting miss-configuration issues. You can also use them in conjunction with the Nmea Playback module so as to replay you navigations later on. They might also but useful for eventual future ScanNav enhancements to analyze your boat's performances. All log files will be saved in the folder indicated in the preferences.
Warning: Intermediate dates are the result of an interpolation between 2 deadlines, and even if they are consistent, they cannot be compared to a calculation from the model. Of course, you always have the option of displaying the model's deadlines by selecting them from the menu.

- The selection of the date is done on the same principle as for the currents, with a Date and Time selector.
- When you change the date in the Grib module, it is also changed in the Currents module, and vice-versa.
- The date is circled in red if the synchronization is impossible (i.e. if the grib and current files are on different time ranges)
- Synchronization is enabled by default. To deactivate it, uncheck the new box “Synchronize with…. » in the currents or gribs settings (general tab)
- The "current date" button is grayed out if the time range of the grib file (or currents) is outside the present date. Thus, if you analyze a grib from 3 months ago, the button will be grayed out because the grib does not contain the present date.
- A new option "use GPS date" in the Gribs and Currents settings allows you to adapt the reference of the current date to that of the track when using the NmeaPlayback module to replay a past track or routing, in accordance with the gribs/currents of the corresponding date.
- Improvements on the Grib download interface
- Fixed areas and User on-screen selection are now integrated in the same interface
- Support of new providers (SailDocs, OpenSkiron...)
- Geographic bounds of models now displayed to put in evidence
- Possibility to filter providers/models.
- Interface with Great Circle subscriptions
- Interface with SailDocs
- Update mechanism to include new models as they are available on the server
- Improvements in the Email interface
- Support of precipitations from Grib files issued from the High resolution AROME and ARPEGE models of Meteo-France
- Improvements of performance on display of transparent layers of Grib and currents modules.
- The Grib Download interface is now launched in another
background
process, letting you continue interacting with ScanNav while
downloading. The User interface remains unchanged, apart from a new "On
Top" option that lets you keep the download dialog on top of the main
window.
- Support of Grib files issued from the High resolution AROME and ARPEGE models of Meteo-France (see Notes below)
- Support of multi-level
data (for example mean wind of Gust,
at surface or 10m). To choose between the different levels click on
data types buttons and choose the desired level amongst the
listed ones in the first menu entry. Example for the wind:
- Support of Gust winds
(wind sublevel), et water temeratures
(temperatures sublevel)
Starting from version 14.0
the GRIB module supports Ocean Current data provided in grib files. The
new button
in the Grib control window has the same behavior as for the other weather
parameters to control the display. Download of Grib currents is
directly integrated in ScanNav from version 15.1 with Grib currents
from the RTOFS model
issued by the Noaa (see notes on providers below)
See also support of Currents grib files issued from high resolution models of
MyOcean , via the currents module. See description
- Sort entries by date to address the problems that occurred with certain providers that provide data unsorted
- Original date of grib file shown in the title bar
- Availability of Météorem records for demo purpose. Can also be used without the GRIB
- The
button in the control box enables a popup window to display information under the cursor at the corresponding geographic location.
Grib Download Interface
The downloading of grib files can be done directly from ScanNav, thus avoiding the extra communication related to browsing web pages.
You can download predefined fixed areas, or select the area on the screen.
Since version 18.1 of ScanNav, the 2 types of download are grouped in the same dialog.
You can access it via the "Options" menu, or button of the grib control box.
IMPORTANT: Since Internet access is done directly from ScanNav, you may have a warning from your firewall that ScanNav is trying to access the Internet. Acces must of course be granted, otherwise the download will not be possible.
The Grib Weather and/or Currents download interface are the same, only the models change. The different models are configurable and scalable, and may evolve independently of ScanNav versions. So it is advised to update the list of models regularly. It is possible to filter the list of models, so as to only display the useful ones. (please refer to the configuration chapter below)
"Dynamic" models (i.e. with the option of selecting an area on the screen) are displayed first.
Then come the predetermined models with fixed zones.
If you don't have the Grib module active, a list of archive templates, that you can use to testing purpose, is shown at the top of the list.
Choose a template from the list of providers. A blue box allows you to view the geographic coverage provided by the model if it does not have global coverage. You can also use button to center the chart on the covered area.
For information on the selected model, click on the link "Infos" at the bottom-left of the window (opens an external web page).
If the model is a fixed model with predefined geographic zone, the parameters are grayed out, they just allow you to view the coverage and available data. Otherwise, you can choose the different parameters according to the selected model:


For SailDocs and SailaMail, the list of forecast times is indicated in the text field according to the parameters. It is then possible to refine by deleting individual times. Make sure not to choose too many time steps, which could end up in a server error.
An estimation of the file size to download is indicated. Although normally quite close to reality it may differ more or less.
Once all options choosen, click on "Launch Request" to start downloading or send the mail, according to the choosen interface for the provider. Note: If the area is not defined, or outside the provided coverage, this button will be grayed out.
Configuring providers
The grib providers starting with the prefix "SN" are hosted on the ScanNav server. Those that start with "GC" are hosted on Great Circle servers. At first use, only a generic "*** Configure Great Circle Models ***" provider is present to configure the subscription. When completed, the list will contain all models present in your subscription.
Please visit www.scannav.com/GB/Gribs.php for more information on available subscriptions and obtain your password.
It is recommended that you update the templates on a regular basis to take advantage of the latest services available on the servers.
To configure and update the model list, click the

- "Filter models" : Lists the models in a new window, each with a check box. Just uncheck the check-box of entries that you don't want to show in the choice list. In addition, if the option "limit to visible area" is checked, models outside the area displayed in ScanNav will not be proposed.
- "Connection Settings" : Opens a new window that lets you configure your connection IDs and download method for the selected provider.

- Enter your username and password in the appropriate fields. If you check the "show" box, the password will be displayed in clear text.
- Choose the download method of Grib files in the field "Request method": Either "Direct connection", or by Email. For models hosted on ScanNav, you can then click the "Test" button to test the settings.
- Click on "Update" to update the list of models available from the supplier according to your subscription. Note: the pc must be connected to the Internet at this time (no update available by email to date)
- The "Filter Ensemble models" option is only available for Great Circle. It allows to ignore the individual variants of the models "GEFS Ensemble" to avoid overloading the list of choices.
- You can optionally change the destination folder where to download grib files. This directory is common to all models of all providers.
For Direct connection mode, the grib file will be stored in the specified directory, and opened in ScanNav upon completion of the transfer (after confirmation).
For Email-based mode, you must set up an e-mail tool that is compatible with the "MAPI" protocol (eg ThunderBird), so that ScanNav can drive it. In case your mail tool is not compatible, a window will show you the fields to be copied / pasted in the subject and body fields of the e-mail message.
The server will reply with an email including the grib file as an attachment. You will need to save the attachment to disk and then open it in ScanNav with the interface intended for (see Grib module main documentation).
Tip: You can also open Grib files with ScanNav directly from the Windows explorer or from an email. To do this, you must associate the extension .grb / .grb2 and / or .bz2 with ScanNav in the Windows settings)
Notes on the different providers:
Grib services hosted on the ScanNav server are free of charge for ScanNav users with the Grib module (and/or Currents module for currents grib). The list of providers below is given as an indication and is subject to modifications. Please refer to www.scannav.com/GB/Gribs.php for an up to date list. And don't forget to regularly update the list of available providers (see Configuring providers in previous chapter).
The server processes certain models such as
MétéoFrance or MyOcean by storing them locally to speed up processing.
Server data is refreshed several times a day to store the latest
forecasts.
For other models such as Noaa, ScanNav acts only as a gateway, the data
being extracted from the Noaa servers at the time of the request and
then compressed before sending. The speed depends on the availability
of Noaa servers at the time of the request.
- Models issued from Meteo-France include the Winds (standard and Gust), Pressure, Air temperature, and Precipitations.
- AROME UHD: This popular model for local regattas covers mainland France at an ultra-high resolution of 1km. Previsions for 36h, by step of one hour.
- AROME:
Covers France and Overseas (Antilles, Polynesia, Indian, Guyana, New Caledonia) at very high resolution (0.025 °), previsions for 36h, by step of one hour
- ARPEGE Europe: Covers Europe at High Resolution (0,1°), previsions for 96h, by step of one hour
- ARPEGE World: Worldwide coverage at 0.5°, previsions for 102h, by step of 3 hours
- MFWAM models issued from Meteo-France include Wind at 10 meters, and Wave information (Height, direction, and period) . Waves can be choosen between Swell, Wind Waves, or Total Sea. The 3 models are:
- MFWAM France: Coverage and resolution identical to model AROME
- MFWAM Europe: Coverage and resolution identical to model ARPEGE Europe
- MFWAM World: Coverage and resolution identical to model ARPEGE World
- Data from NOAA are obtained directly from NOAA by the ScanNav server.
- NOAA GFS: (Wind, Gust, pressure, rainfall, temperature) global coverage at 0.25°, 0.5° or 1°, previsions up to 15 days by step of 1hr or more
- NOAA Wave: Wave model (wind, swell) global coverage at 0.16° and 0.25°, previsions up to 15 days by step of 1hr or more
-
Great Circle is a provider of high resolution gribs. A subscription must first be taken out directly on their site (http://www.greatcircle.be/index.html). Then all you have to do is enter your login details in ScanNav (see above), and you will have access to the different models corresponding to your subscription.
- SailaMail is a provider that also proposes free GRIB files from the NOAA GFS and Wave models at a resolution of 1° available by mail.
- SailDocs is also interfaced for several models (to date: GFS/WW3, Coamps, RTOFS)
- OpenSkiron Starting from version18.1, you also have access to fixed area grib files proposed by OpenSkiron. It is nevertheless to be noted that these files can be quite voluminous, you should therefore use a stable connection to download them.
- RTOFS Model: This model from the Noaa is accessible through SailDocs, at a time step of no more than 24h. As opposed to tidal currents that provide more details, these are Ocean Currents and are essentially useful for oceanic crossings. This model can be downloaded with the Currents or Grib modules.
- Several other Ocean currents data sources exist, especially those from the OSCAR model provided by the NOAA.
You may get them by mail or other means, for example see the following link: http://www.svsarana.com/oscar/
- For finer currents data, please check in next chapter the models available with the Currents Module
New features in version 16.0:
New features in version 15.3:
New features in version 15.0:
- Choice of the time system: Starting from version 15.0, it is possible to choose the time system displayed in the Currents control window: either UTC, or Local (settings from your Windows system)
- Support of GRIB currents files:
Starting from version 15.0, the Currents module can read currents data
from Grib files of various providers. Unlike the existing SHOM UJA data
which have no date limits, GRIB files
cover a limited period. If you move the cursor outside of this period,
a warning will be displayed, and the date will be repositioned at the
GRIB's limit date. As for the SHOM data, it is possible to select a
specific entry in the list, or let ScanNav interpolate between two
dates. Download of Grib
files is done directly from the Currents control Window. Click the
button and then select the "Download GRIB files" entry. The interface then works exactly the same way as for the download of Weather GRIB files. You just need to choose the model; Define the area on screen; and Launch request to start downloading. Please refer to the related documentation " Download by Screen selection" for the Grib module.
Older Enhancements:
Since
version 9.0, currents areas can be opened directly by right-clicking on
the map and using the "Tidal currents" entry of the contextual menu
which will show the list of files available for this area,
sorted from the most detailed to the most general.
Note: if the sub-menu "Tidal" does not appear, verify that you are on a
geographical area covered by the zones of UJA SHOM
The
button in the control box enables a popup window following the cursor
and showing currents information at the corresponding geographic
location.
Starting
from version 10.0, the tides module is interfaced by default
with
SNTides, which is based on the kernel of SHOMAR (©
SHOM 2010 Contrat n° 114/2010). It is limited to the 2 consecutive
years following the edition date (up to 2011 included for version
released in decembre 2009). You still can use WXTide to
calculated
currents for further dates. For this, set the "Tides Source" parameter
to "WXTides" in the general settings for the tides module.
Don't
forget to reposition it to SHOMAR when done, so as to benefit of a
better precision for dates before the limit.
For complete documentation of the SNTides
module,
please refer to the pdf
document.
GRIB currents providers:
The Currents module now integrates currents data issued from MyOcean models. The original data is processed several times per day by the ScanNav server to convert them in Grib format. For a description of the available models, please see the Currents module page on the ScanNav web-site.
Note: The list of available models changes regularly, and independently of the versions of ScanNav. Remember to update your models! (see Configuring providers in the Grib chapter above)
Note: Please select reasonable sized areas to limit the size of downloads and necessary processing on the server. Some models are restricted in geographic area size to limit errors. If this limitation is too restrictive, please contact us to define your need.
ScanNav is also compatible with other sources of Currents in Grib format available on the net.
New from version 21.0
- Objects window: The contextual menus (right click) on the different objects are enriched, in order to offer different operations on the selected elements (details, analysis, export, ...). The left part of the window now also benefits from the contextual menu, as well as any filters.
- Contextual menu on the map: It is now possible to export objects in different formats directly from the contextual menu. You can also perform an action on several objects at the same time, thanks to the new entry "Selection" of the contextual menu. The chosen operation will then be performed on all the selected objects. The "selected objects" designates the elements previously selected with the selection tool, and/or all the elements intersecting the clicked point.
- GPX Export: You can now choose to export objects in GPX format with or without the ScanNav extensions, these being problematic for some software/GPS. All you have to do is check or uncheck the "Include ScanNav extensions" option in the file chooser that opens to choose the name of the exported file.
New from version 20.1
New possibilities for Notes (text)
It is now possible to assign a font, size, and angle to each Note individually. The settings are made via the properties box (new fields available to choose the font, size and angle), or interactively with the modification tool (see below)
Interactive transformation of objects
Select the "transformation" tool from the toolbar, which will let you edit graphically the different types of objects. The applied transformation depends on the type of object, and on the use of keyboard keys.
- Moving Waypoints, Notes, Bearings and Filled Zones: Click on the waypoint, note, segment of the bearing, or within a zone with a fill pattern, move the mouse, and release the mouse at the new desired position.
- Moving unfilled areas, or routes: while pressing the <alt> keyboard key, click on the outline, move the mouse, and release the mouse at the new desired position.
- Adding / Moving points on a route, area, or bearing
- Click on a point on the route / area / bearing, move the mouse, and release the button at the desired position
- Click on a segment between 2 points to create a new point (except for bearings, where this operation moves the bearing)
- To add a point at the beginning or at the end of a route, while pressing the <ctrl> keyboard key, click on the first or last point of the route according to the desired operation, move the mouse, and release the button at the desired position for the new point.

- Possibility to configure the type and size of the lines of the tracks / routes / bearings / areas, and to fill the Danger Zones with a pattern
- Possibility to setup the alarm sounds using either a sound file or a buzzer configurable in duration and frequency.
- The size and filling of the boat icon are now configurable (via the heading line configuration tool)
- Simplified adding custom waypoint icons with support of png files for icons, with predetermined transparency


Formerly reserved for waypoints, this feature is now (from version 20.1) available for all types of objects.
Starting
from version 12.1, it is possible to associate an unlimited number of
links to a waypoints (was limited to one in previous versions).
- One photo stored locally, that will show up when overring the mouse over the waypoint.
- One or more URL to any active contents (remote web sites, or local files), with a specific title.
- Open the Waypoint property dialog
- Click on the "Photo/Link" button
- A Dialog box will let you enter the location of a photograph, and as many URL as you want.
- For each URL, enter a title, and the url. This can be an url to a remote web site, or the path of any active content file (video, word document, pdf, etc...)
- When moving the mouse over the waypoint, a popup window will appear and show in the following top down order:
- the text comment of the waypoint
- a preview of the photo if any
- the list of links (one per line) provided.
- When clicking on the photo preview, it will be opened full size in a separate window
- When clicking on the links, the active content will open in the associated application (web browser, multimedia player, etc...)
A safety margin to take the rule of the thumb (1)
In general, the browser takes two lines of security, a vertical that is called the pilot's foot, the other horizontal which is to move to a distance of submerged dangers. The user of the GPS will continue to take these two margins, and to apply the second rule of thumb: It provides, whenever possible, its path in order to spend more than an inch of submerged hazards at the scale which he serves.
This rule is a bit harsh in the port approaches that have been surveyed recently. In these areas, the browser will be able to enjoy fully and lucidly the accuracy of GPS.

The "thumb" activates / disables the menu "Options" -> "Cursor" -> "Rule of thumb" which opens a dialog box to configure the virtual radius of the thumb and the display type (circle completed or not).
The measurement of the radius is expressed in centimeters relative to the printed paper to its original scale. On screen, the circle will be more or less depending on the level of zoom on the map.
Note: The thumb will not display for maps with a scale of origin is not known. (all charts containing this information)
Version 12.1 brings several major enhancements on the MOB function
- NKE MOB system interface
- By default, ScanNav is set to listen to the NKE MOB sentences. You may deactivate it in the "Navigation" tab of the preferences, by unchecking option "Watch NKE MOB"
- An alarm will be raised on reception of any of the 2 following NMEA sentences:
- $PMLR,05,01,02,0337*02<cr><lf>
- $TRWPL,,,,,MOB*21<cr><lf>
- General MOB system enhancements with dead-reckoning of the MOB position according to a given drift.

- The audible alarm may be switched off by unchecking "Audible alarm" option.
- The navigation control is set to navigate towards the MOB position. This includes repetitors, and the autopilot if it is interfaced
- In case of areas with currents, you may set the speed and direction of the current so as to estimate the position of the MOB during time: A second waypoint is then created which will move according to the dead-reckoning system.
- You may then choose to navigate towards the "Estimated position" or the "Initial MOB position".
- the MOB initial position, date of MOB, and time since MOB are displayed
AIS and DSC MOB beacons interface
The AIS and DSC MOB beacons interface uses the same concepts as the NKE MOB, bringing in addition the real time updating of the MOB position through the AIS or DSC signal.Please refer to the new AIS documentation.
The tool is used to create bearing lines. Click on the map on the landmark, and move the cursor while keeping the mouse pressed, then release at the end of the bearing line. By clicking on a point and releasing the mouse right away, a bearing between the clicked point and your current position will be initiated.

You can also define the angle of the bearing and the segment length (in nautical miles) before validating.
The bearing angle can be displayed in True or Magnetic bearing and/or Inverted according to your choice.
It is also possible to reverse the bearing using the "Invert" button, i.e. the end of the line becomes the point of bearing.
You can later on modify a bearing by opening its properties box, or by using the modifications tool:
- click on the segment to move the bearing line
- click on one of the 2 ends to change the bearing
An Anchorage Area is very similar to a Danger zone, the main
difference being that an anchorage area raises an alarm when exiting
the zone, while a danger raises an alarm when approaching and/or
entering the zone. On the other hand, it is possible to have only one
active anchoring area at a given time, whereas several danger zones can
be active simultaneously.
Version
17.0 adds the possibility to automatically call your DSC VHF
radio when in Anchor Drift Alarm conditions. Please refer to the documentation of the AIS/ASN/ARPA
module
An anchorage area can be defined in one of the following ways:
- With the new tool
Available by creating a custom tool-bar. Click on this button, a circular area is created around the position of the boat. Simply fill in the desired turning radius, and validate.
- Similarly to danger zones (tool
), Just check the "swing area" option instead of "danger zone" in the properties dialog box of the area
- It is also possible to create a circular area with the
tool
:
- If the danger zone has only 2 points, the first point will be the center, and the segment defines the radius of the area
- If the danger zone has only one point (double-click on the map), a circular area is created, centered on the point, and with it's radius set to the last value of anchorage area
- It is possible to
transform an area of danger anchorage area, and vice versa by switching
the "swing area" or "danger zone" in the properties dialog box of the
area.
Starting from version 12.1, you can dynamically tune the level of priority of charts, so as to display higher or lower detailed charts, still keeping the same level of scale on screen.
- To open the charts priority control, use menu "Options" -> "Charts priority"
- Move the cursor to the right to use higher scale charts and to the left to use lower scale charts.
- The "Reset" button lets you reset the default central position corresponding to the typical standard scale level.
"Long Press" : Replaces the rignt-button click. Press and hold your finger on the screen one or 2 seconds before releasing to show the context menu or other "right-click" related feature.
"Pinch Zoom": Replaces the mouse wheel. Move 2 fingers appart / toward each other to zoom forward or backward.
"Pan/Scroll": Replaces the mouse middle button. Drag 2 fingers together to move around the chart without having to select the hand tool.
- All the repeaters can be displayed in transparency, which allows to see the map below
- To adjust the transparency level, go to the properties of the repeaters, then move the "opacity" slider to the right for more opacity, or to the left for more transparency.
- By checking the box "apply to all", the opacity level applies to all repeaters at the same time.
- The GPS simulator has been reviewed in particular on entering positions, and behavior of the double-click on the map that positions the boat and updates the course simulator.
- Ability to find invisible objects via the submenu "invisible objects" of the context menu (only appears if invisible objects are present)
- Bearing segment distance is now present in the Bearing tooltip
- The zoom tool now displays the result centered instead of left aligned on screen
- Several ergonomic improvements have been made to the Routing module, in addition to new concepts. See the documentation for the Routing module that has been updated.

- If the "Include the world global shoreline" option is checked, the default small scale world coastline will also be added to the library. It is advisable to keep this option in order to maintain small scale global coverage.
- Check the "Add to the current library" to add the selected library to the existing one instead of resetting to start from a blank library.
- Check "Display full paths" to show the full folder name in addition to the file name Note: It is possible to select several entries, but it is not recommended to use different types of charts on the same area (for example SonarChart and NauticalChart), because ScanNav will switch from one type to the other without control. This possibility is especially useful for loading multiple geographical areas at once.
Contextual menus:
This clarifies on which object the actions are taken. Indeed, in the previous versions, entries were all inline in the menu, and it was not always clear which object it concerned. Above all, it now allows to interact with different objects intersecting the clicked point, which was not possible before. For example, clicking on a route waypoint, you can interact on the waypoint, or on the route.
Clarification of menus Export and Save...
"Export in Native format" now replaces "Save selected" which was confusing, as it is indeed a partial Export dependant on the selection and also the current selected tab. In counter part, "Save All" was renammed "Backup Objects Library", as it is a full backup that can be restored with "Restore Objects Library".
All Export menus are declined in "Selected", or "All".
- "All" means all entries appearing in the list of objects of the current Tab. For example, if you are in the "Objects" tab, all objects will be exported, but if you are on the "Routes" tab, only Routes will be exported.
- "Selected" means
just entries that are selected, i.e. highligted in blue.
Clarification of waypoints visibility scale, and choice of Waypoints Symbols:
- Zoom, Hand and Selection tools no longer gray out other tools
- The zoom tool has been improved to reduce the number of icons:
- single click = zoom in x 2
- single click + key <ctrl> = zoom out / 2
- The zoom in and out tools can therefore be removed from the toolbar (keyboard shortcuts are still valid)
- Configurable keyboard shortcuts (Specific request for fishing):
- configurable keyboard shortcuts to create instant waypoints with specific symbols. The keys q s d f g h j k l m w x c v are set by default, see comments in the file Accelerators.txt to modify or add them.
- Possibility to save (and display) the
track only by sections. (the question is asked during
gps activation / deactivation)
- Multi-window has been improved to display different views of the map and in different modes (for example a window in automatic mode and the other in manual mode)
- "Disabled" charts in the library may be displayed in manual mode, using the context menu ("Inactive charts" entry)
Starting from version 15.3, you have the possibility to take in account the magnetic compas heading in the boat icon and heading line. The heading line length can now be parametrized in length, either in time or distance.
The Heading line preference dialog has therefore been adapted accordingly:

- "Compas": The heading of the boat icon will be according to the magnetic compas, and if the heading line is checked, a second heading line representing the compas heading will be displayed in addition to the ground heading line.
- "COG": The compas will not be taken in account in the heading line.
The Heading line and graduations are only displayed when GPS monitoring is active. They can both be parameterized in length by time or distance, and in different units by selecting the corresponding options.
In order to lighten the display, the graduations are only displayed if the gap between them is not too tight. The number of graduations is also limited to 10 (configurable on demand).
New feature in version 15.0:
A new more standard scale chooser

It lets you choose the display scale using the standard conventions 1:XXXX used in paper charts, either by choosing a value in the list, or by entering the wanted scale followed by <enter>.
Although this new tool is used by default, it is still possible to use the former distance scale tool. To activate one or the other tool, go in menu "View" and choose entry:
- "Standard scale" : to use the new standard scale tool
- "Scale in distances": to use the former scale tool based on distances on screen
Both tools may also be used at the same time.
Please refer to the main documentation for a decription of the "scale in distances" tool.
The Visible Area tool has been reviewed in version 18.1 of ScanNav, and moved from the "Operations" menu to the "Option" menu. It now consists in a non blocking window that can remain open to facilitate it's reusability.

This tool lets you display in ScanNav a view centered on a given precise position and scale.
Enter the central position and scale of display, then click on button "Apply"- You can choose the input unit of the position between Decimal Degrees, Degrees/Minutes, or Degrees/Minutes/Seconds.
- Scale can be given in standard chart scale, or in covered distance between left and right of the screen.


The routes included since version 8.1C4 a planning tool with calculation of ETE / ETA on the road with the possibility to assign speeds for each segment. This is done in the properties dialog of routes:
- Click on the speed of a track segment already selected (highlighted in blue) to change its value, ETE and ETA are then recalculated.
- You can change the speed of several segments at once using multi-line selection


- Click on the date of a selected waypoint to amend the ETE other points are then recalculated
It is also possible to duplicate a route to facilitate the creation of a new route from an existing one: right-click on the route (on the maps or in the list of objects), and choose entry "Clone route"
Clarification of membership of waypoints to routes
In the "objects", the waypoints are now displayed with different colors depending on their belonging to a road or independent
- black: independent waypoint
- blue: independent Waypoint used in one or more roads
- green: waypoint from the current route (in the routes details)
- rouge: waypoint from another route (but also used in the current route)
Starting from version 12.1, you have the possibility to split tracks in different segments, and/or join different tracks into a single one.
Before starting to manipulate, it is strongly recommended to save your existing tracks in a separate file as a backup; you will therefore be able to recover them in case of wrong manipulation.
1) To split a track in 2 segments: use one of the following possibilities:
- Right-Click on the track in the chart display at the location where you want to split it, and choose menu entry "Split track in 2"
- Or in the track details view of the objects window, right-click on a trackpoint and choose menu entry "Split track in 2"
2) to join 2 (or more) tracks in a single track use one of the following possibilities:
- The easiest way: In the "objects" window, select the tracks to be concatenated, then use menu "Edit" -> "Merge tracks" (you can also right-click on the selected tracks and use the contextual menu)
- Or on the chart, select tracks to be merged using the "Select" tool (use <Control> key to do multi-selection), then use menu "Edit" -> "Merge tracks"
Warning: merging of tracks is done according to the start/end time of tracks, and removes any overlapping time period in the second track.
You can fine tune the size of different elements of the interface, as well as texts displayed on the charts giving you a better reading, especially on Ultra High Resolution screens. As a general topic, default sizes for the different texts and icons are initialized according to your screen resolution to give you an appropriate reading. You may then tune most of them if the defaults doesn't suite you.
1) Tool bars buttons size:
Right-click on any tool bar and choose the "Buttons size" entry in the contextual menu to display the following window. Initial settings will depend on the resolution of your screen. Displayed values are in pixels
Icons Size: Move the ruler to the right to grow the icons size.
Horizontal and Vertical Margins: increases/reduces the space around the icons without scaling images.
Borders Thickness:
Lets you change the pressed buttons borders thickness to
better distinguish them.
Pressed buttons color:
You can assign a specific background color to buttons when in
the pressed state, so as to distinguish them even more.
NOTE:
It is advised not to use red,yellow, or green colors, as they are used
to put the GPS state in
evidence (see previous chapter).
Button style:
By default tool bars are now flat (no frame between
icons). Check this option to revert to the previous look with buttons aspect.
Default Values:
Click this button to revert to factory settings. Default values depend
on your screen resolution so as to propose the most adapted sizes.
Apply to All: Applies the
current settings to all tool-bars. Avoids having to customize each
tool-bar individually if you want the same settings for all tool-bars.
2) Common texts fonts:

For each type, you may choose the font type, size, and attributes (Bold / Italic / Underlined)
"Default Values" let you revert to factory settings.
Small:
-
- Labels for gribs and currents displayed on the chart
- Labels for the different gribs and currents scale bars
- Labels for the Mercator graticule
- Waypoint names displayed on the chart
- graticules and labels for the Wind indicator and Heading correction displays
-
- Used for Popup Infos contents
- Used for simple text Displays and texts inside the Wind indicator and Heading correction displays
-
- Notes objects displayed on the chart
3) Scaling Waypoints icons:

Also available through the "Other" tab of preferences. A new ruler lets you scale waypoint icons.
Note: The scale factor is global to all waypoints, without distinction (no possibility to date to scale icons individually).
4) Precision of object selection:

5) ENCs fonts sizes:
You could already customize the fonts used in ENCs with previous versions. It nevertheless needed to be done systematically on Ultra High Resolution displays in order to have a readable result. This is no longer the case, default values now adapt themselves to the screen resolution and should look globally the same whatever your screen resolution is.The size of symbols displayed inside ENCs adapts automatically to the screen resolution so as to display at an appropriate default size. From version 21.0 it is also possible to apply a scale factor with the "Symbol size" slider in the preferences.
6) Navionics charts text size:
Note: This concerns the old Navionics component for XP. From version 21.1, refer to the documentation for the new Navionics component.
To grow icons sizes, use one of the "Easy View" display settings.
- Automatic backup (auto-save) (starting version 19.0): The objects are saved periodically in order to preserve from unintentional pc shutdown/crash. The backup is performed as background process and does not interfere with real-time operation.
- Archiving: The automatic archiving of objects allows you to return to a previous state by restoring your objects at a given date, in case of mishandling, or other loss of data. Unlike the "auto-save" that happens in the background while running ScanNav, and overwrites the previous version, Archiving only happens when exiting ScanNav, and the data is retained for eventual subsequent recovery. The automatic archive can be generated either according to a user-defined period (by default 7 days), or in case of a ScanNav crash. There are therefore two types of archiving:
- Periodic Backups: They are created from a copy of objects when saving, in folder "[Documents]\ScanNav Settings\SavedConfigs", and with a name reflecting their creation date. For example "BackupObjects_2014-11-22_22h22.zrw" for a backup on November 22nd 2014 at 22h22
- Crash Backups: Those are generated in case of a crash, and contain the objects present at the time of the crash. Warning: this backup might be incomplete according to the severity of the crash. They are located each in a different sub-folder of SavedConfigs with a name reflecting the date of the crash. For example "[Documents]\ScanNav Settings\SavedConfigs\Crash_2014-11-15_02h30\curobjects.zrw" for a crash that happened on November 15th 2014, at 2h30.
The period of auto-save and automatic archiving can be defined in the "Other" tab of ScanNav preferences with the following:

- Check options to activate the auto-save and/or archive
- Define the period in
- number of Hours or Minutes for auto-save (default is 10 minutes).
- number of Days or Hours for archiving (default is 7 days).
- The Backup happens if the previous backup is older
than the current date increased by the defined period, at the time of saving objects
(i.e. when existing or saving explicitly). There is no intermediate
backup inside a ScanNav session.
- Defining a period of 0 (days or hours) will result in a backup done for each session or explicit save. To deactivate the automatic backup, uncheck the option instead.
- Backups are never deleted by ScanNav. You therefore might want check the allocated disk space periodically, and remove backups manually when not needed anymore.
To restore a backup or any other objects file, use the "Restore Objects Library" menu entry, accessible from the "File" menu in main window, or the Objects window.
WARNING: this will replace all your existing session objects that will be lost (except if you did a backup previously)
You may also use the "Insert Objects" that will preserve your existing objects. Routes and Tracks might in this case contain some double entries that you can remove afterwards.
Starting from version 18.1
Nautical guides and Object layers are grouped in the same window, with a tab for layers, and a tab for Guides.
To open, use button from the toolbar.
This window is now non blocking, which lets you quickly activate or deactivate layers without having to go in the menu. You can also resize it to take more or less space on screen.
For a description of novelties and full documentation of guides, please refer to the pdf documentation. New guides are added on a regular basis, the latest at the date of version 18.1 release concerns the integration of the SHOM wrecks database integration.
Layers coupled to Classes:
Layers are automatically created based on the class assigned to objects in their properties.
Layers can have multiple uses. Their purpose is to be able to show / hide a group of objects alltogether. An example of use can be to assign a default class for a given navigation season, so you can show or hide all tracks and other objects created during this season with a single click.

The existing layers are listed in the bottom part. Just check/uncheck the corresponding checkbox to show/hide all objects belonging to the same class. You can use multi-selection with the <Ctrl> or <Shift> keys of the keyboard to change several layers in one shot. A gray checkbox (like the first entry in the example opposite) means that only part of the objects from this class are visible. It is indeed always possible to display / hide individual objects independently using the objects property window.
To refresh the list, use the button on left bottom side of the window.Starting from version 14.0, the Objects window integrates a new search and filter function. This lets you easily find objets according different criteria, and not overload the list with invisible items. This function is also available in the Routes properties window, using the 'Filter" button.
- Text filter:
You can filter objects by just typing part of the name in the text
field. The search can be made on on ore more fields, such as the
object's Name, Comments,
or Class.
(check the appropriate options). No filter is applied if the field is
empty or none of the 3 options are checked. Filter can be case
sensitive or not.
- Filter by Visibility:
check the "Visible" option to
only show objects that are visible.
- Filter by Distance: check
the "Distance"
option, and give a maximum distance in nautical miles above which
objects will not be listed. When used in the Objects Window, the
distance is calculated from the location at the center of the screen.
When used in the route properties window, it is calculated from the
last selected (clicked) point. No filter is applied if the option is
unchecked, or if the distance is set to 0.
Note: The filter is not refreshed dynamically when panning the map on screen. To refresh, modify any option (for example check/uncheck any option)
Starting from version 13.1, You have the possibility to overlay web layers (Aerial/satellite images or other) in transparency over the charts, this with just a simple click. For a full description and documentation, please refer to the pdf documentation
- You can also visualize the current view in Google Earth (right-click menu on the map + 'GoogleEarth')
- It is also possible to display objects (routes, tracks, waypoints etc ...) in Google Earth. Very useful for sending your tracks to friends who are not fortunate enough to own scannav
- Either right click on a track (or wp etc.) on the map or in list view, then "Google Earth" from the context menu
- Or select one or more objects, and use menu "Operation" -> "View in Google Earth"
- It is also possible to frame a view in Google by pressing the F11 key on the keyboard and draw a rectangle. The area claimed will appear in Google Earth, visualized with 4 points corresponding to four corners of the rectangle. This will retrieve copies of screens to integrate easily as "pseudo" chart in ScanNav. See chapter "Workshop - Georeferencing" later in this document.
ATTENTION Google Earth Screenshots are not real marine charts and should not be used for navigation. However, they constitue and additional help, especially in certain regions of the world where recent maps are lacking. You will find below a small process to apply for quick results.
- Install good screen capture software (eg Gadwin PrintScreen)
- Configure this to take the active child window, and to save in a directory in jpeg format
- Start Google Earth, and configure it (display menu) so that there is the least amount of text and layers (compass etc) on the map (remove the status bar, etc ...)
- In ScanNav in navigation mode, press the F11 key then draw the rectangular area you want to capture
- ==> The defined view will be displayed in Google Earth, with 4 visible points corresponding to the 4 corners of the rectangle defined in scannav
- Go to Google Earth in full screen (F11 key) in order to have the largest possible area displayed.
- You can possibly readjust the view slightly by zooming / moving but making sure that the 4 points are still visible. In any case, Be careful to always keep North up, and zero tilt.
- Take the screenshot and save the result in Jpeg.
- In ScanNav, switch to Workshop mode on a new document, and insert the image
- Launch the georeferencing tool, go to the "Points" tab, then press the "Latest Google points" button to initialize the geographic positions of the 4 points.
- Click on "Apply" to have a first approximate referencing (allows to use "visualize" to move on the 4 points)
- All that remains is to move the four points to superimpose them on those entered in the screenshot, taking care to select the "Point displacement" mode (see " Workshop - Georeferencing" below in this document)
- Don't forget to press "Apply"
- Enter the general parameters of the map such as the name etc ... (the projection must be Mercator, and the Datum WGS84)
- Save the result.
To export / import objects in GPX format, you can use:
- The overall method using the menu "File" from the main window to export all objects,
- The selective method using the "File" menu from the Object window. Here you may export selected items.
The file must meet a list of prerequisites in order to be interpreted by ScanNav.
- The first line in the file determines the type of information for each column, and must match the following keywords. Fields are case insensitive. Those marked with an asterisk are mandatory.
- "Name" or "Nom" (*): name of the Waypoint
- "Latitude" (*): Latitude of the waypoint, see description of accepted formats below
- "Longitude" (*): Longitude of the waypoint, see description of accepted formats below
- "Class" or "Classe": If this column is present, it determines the class of the waypoint. If the column is absent or its value is empty, the name of the imported file determines the class of the waypoint.
- The content of columns with other identifiers will be added to the waypoint as a comment, prefixed by the column title if it is not empty.
- The following lines correspond to one waypoint per line. To insert a carriage return in a field, use the escape characters '\n', otherwise ScanNav will try to interpret the 2nd line and following as different waypoints.
- To generate an import text file, the easiest way is to fill it in Excel or another spreadsheet, and export it in "CSV" format (text separated by a delimiter)
- Lines starting with the '#' character are considered comments.
- The export must be performed with the following parameters:
- Character set: "Western Europe (Windows-1252/WinLatin 1)", or "ISO-8859-1".
- Field separator: "{tab}", or ";". Please note that the fields filled in must not contain this character, otherwise it will be considered as a column separator.
- Character string separator: must be empty, not supported by ScanNav.
- 51° 03,7’N / 51° 03,7’S
- 51° 03'7N / 51° 03'7S
- 51° 03,7N / 51° 03,7 S
- 51° 03,7 N / 51° 03,7 S
- N51° 03,7' / S51° 03,7'
- 51° 03,7 / -51° 03,7
- 51.0616683959961 / -51.0616683959961 (decimal degrees)
- the decimal separator can be '.' or ','
- the characters ° and ' are optional (unless used as a separator as in 03'7N)
To import a waypoints file in text format, use the entry "Import Waypoint from Text format" in the "file" menu. At the end of the import, the waypoints properties window is displayed, which allows you to modify some additional parameters.
- Support for the latest Garmin USB models
- And for RS232 models, Garmin protocol support for real-time navigation tracking (avoids having to change the protocol on the GPS when switching from real-time tracking mode to transfer mode, and vice versa)
- There are now three choices in the GPS tab of preferences for Garmin GPS:
- Garmin - NMEA: corresponds to the previous RS232 mode switching the GPS between NMEA for real-time tracking and Garmin mode for transfer mode
- Garmin - GRMN (RS232): also using a COM port, but the protocol of the GPS should be set to Garmin / Garmin permanently
- Garmin - USB: for Garmin GPS connected via USB
- Partial implementation for the transfer of waypoints and routes to the FURUNO GPS.
- Taking into account the magnetic heading in VTG NMEA sentence (when True heading is not present)
- Workaround for some instruments providing a bad checksum:
the checksum button is now a tri-state button :
- checked: a valid checksum must be present in the nmea sentences. Any sentence without checksum or an invalid checksum will be ignored.
- checked in gray: accepts all sentences without checksum, but if a checksum exists it must be valid
- not checked: this mode should only be used exceptionally when an instrument sends invalid checksums. No checksum verification is then performed.
- Import as waypoints of the wrecks database from the SHOM cdrom (use text import described above). Note: Unless there is a specific need, it is preferable to use the guides functionality which now integrates the wrecks of the SHOM. (see guides documentation)
- Support Photo oblique referenced as Waypoints Maptech
Please refer to the updated documentation in pdf
Introduced in version 12.0 of ScanNav, Graphs let you analyze the different
navigation parameters captured during your trip (according to the interfaced instruments).
Version 19.0 brings additional advanced possibilities.
For a detailed description and documentation please refer to the pdf documentation
The new SAR module, available from ScanNav version 19.1, is intended for rescue professionals or volunteers at sea, such as SNSM. Please contact us for more information.
The new Radar Overlay module designed to work with Koden brand Radar-PC, is available in Beta version from ScanNav version 20.0. Please contact us for more information.Warning: Outside the framework of assistance by the support team, it is strongly advised not to modify the options present in this window
Modifications were made to the on-screen rendering engine in order to improve the fluidity, as well on tablets as on PCs. The default settings should suit most configurations. However, if you have a powerful PC, or conversely an older small configuration, changing these settings may improve the user experience. These settings are accessible through the menu "Options" -> "Render options".The display is now calculated for the entire screen plus a certain margin, before being displayed on your screen. To return to the previous behavior, uncheck the "Buffered rendering" option. The display will then be done directly on screen which may cause little jolts, especially on tablets when using Vector charts.

The refresh rate is specified in milliseconds. It corresponds to a delay before ScanNav recalculates the screen image after moving or zooming, so as to avoid jolts. This delay may possibly be decreased on powerful configurations.
Intelligence points for georeferencing allows you to move a point without changing its Latitude / Longitude

- Replacement Item: click on the map the selected point is moved and values Longitude / Latitude modified accordingly (default behavior of the previous version)
- Moving Point: Click on the map the selected point is moved, but the values of Longitude / Latitude remain identical
- New Item: A new item is created, the values of Latitude / Longitude are initialized according to the current geo (identical to the old check box "New Item")
Please refer to the main documentation for other functions
The "Latest Google points" is displayed only if a view in Google has previously been requested (see Chapter Highest Google Earth), otherwise it is absent. By clicking above, all points are replaced by 4 points with their geo Latitude / Longitude initialized around the last area requested Google Earth (with F11). Points reference the 4 corners of the screen.This allows you to quickly reference a Google screenshot, you only have to reposition the four points on the image, taking care to select the "Move Point" not to change the longitude / latitude
Installation
The installer has been completely revamped.
- ScanNav is now installed by default in the directory according to the standard Windows ( "C: \ Program Files \ Marc Lombard \ ScanNav on a typical configuration of Windows).
- By default, no file is created in the installation directory. They are located in the subdirectory "ScanNav Settings" directory standard "My Documents" in Windows
- In the same way all the parameters written in the registry are in the section reserved for the current user
- ScanNav is now compatible with a user account rights retreints in XP Pro
- ScanNav is Vista compatible
Improvements ownership: In the first loading scannav (or when the library card is empty), the library card demo is loaded automatically, eliminating the "syndrome of the blank page." (This assumes of course have downloaded the full version contains maps of demonstration)
Version available in Italian
ScanNav is now available in French, English and Italian
Interfacing with Google Maps: Right-click on the card, an entry "Google Maps" in the menu. Enabling this entry shows a satellite picture of the location via Google Maps. This requires, of course, be connected to the Internet.
Support photos georeferenced MrSid format (more info here)
- Support aerial photos of the French coast in Lambert projection (http://siglittoral.test.application.equipement.gouv.fr/) through a passage in module import Lambert (more instructions here)
- Support satellite photos from NASA projection UTM (download from https://zulu.ssc.nasa.gov/mrsid/, global coverage)
- Requires an extension of license free and available upon request at the moment
- Requires an additional module for more instructions, see here.
Integration of an update patch. The principle is as follows:
- The patches are stored in a single directory. By default, this is the subdirectory "Correction" of the installation directory ScanNav. You can change this folder in the Preferences tab "Loading cards". (In what follows, the name of this directory is implied if not specified)
- The patches will load automatically, depending on the file name of the card. Thus, it is very important to give the names of significant map files, and all different. For example, if you have 2 cards in different directories named toto.map (C: \ carte1 \ toto.map and C: \ carte2 \ toto.map for example), they will all look the same 2 hotfix related to " toto.map "(ie without taking into account the directory name) which pose a clear problem if it is not strictly the same card. It is possible to globally disable or patches by checking the "search for the patch cards ..." in the preferences (tab "Loading cards"). In this version the maps already loaded should be charged for the change to be effective. (In navigation mode it is best to revive scanNav).
- There are 2 types of corrections:
- Georeferencing patches: the patches general (georeferencing, datum, zone waterway ...) There is one file for this file, for example card 7070.map ", the file will be named" 7070 . map_cor.map. This patch does not require images, there is no associated directory (7070.map_cor_files).
- Image patches. These mini-maps (eg from the "Export minimap") from adjusting and superimposed on the original map: there are as many pictures as patches, corrections are indexed on 2 digits, from "01". For example, to map "7070.map" we can find 2 patches named "7070.map_patch01.map" and "7070.map_patch02.map. Also associated subdirectories (7070.map_patch01_files and 7070.map_patch02_files) containing images corrective. The corrections are incremental, ie a correction of higher index appear on top of a correction index lower.
- Creating patches is a
workshop mode.
- Fixes georeferencing, waterway area, etc..: Loading map mode Workshop, make the appropriate changes on geo-referencing, and save the result with the new entrance to the "file" menu: "Save geo fix". A dialog box "save as" opens on the patches directory with the file name prepared as defined above. It remains only to confirm.
- Image patches: Use the "Export Zone" (menu "functions") as described in the literature to create a "mini map". In the dialog box to save the result, the patches directory and the name of the minimap is prefilled based on the name of the chosen card, and patch already. For example, if the patches 01 and 02 of the card 7070.map are already present, it will 7070.map_patch03.map. Just so as to validate the geo backup. Then as described in the documentation of mini-cards with the image change Navcor, paint, etc.. The minimap is then loaded automatically, there is no need to integrate it into the library as before.
- In Navigation mode, it is now very easy to open up a map to check /
correct mode Workshop. Simply click the right mouse button and select
the "Open Mode Workshop" without having
to browse the disk to search.
Support of
Jpeg format and PNG format for entry into
the workshop:
The scanners deliver the most part jpeg and png images, these formats
were added to the list of formats supported.
Note that JPEG is an image format that, even if he has a good
compression rate on disk, taking up much space in memory (24 bits,
compared to mapping formats 4 or 8 bits).
It would therefore make a reduction of color
to these images to optimize their use.
The same is true for some variants of the png (or tif).
Mechanism for the protection of objects
(waypoints, etc.).: Objects can be "protected" to avoid bad manip
deletion, moving, etc..
involuntary. Simply click the new box
"protected" in the properties of the object.
Other protection against handling errors:
- A confirmation is required before any removal of items
- The objects are saved within the
curobjects.zrw "at the end of the session, or on explicit request.
To
avoid
problems related to poor preservation of this file (such as lack of
disk space, or crash Windows when saving, etc..), The previous version
was first renamed "curobjects.zrw.bak" before to perform the backup.
In case of disappearance of objects, it is
possible to restore the previous version.
However:
- Warning: file curobjects.zrw.bak did not recall that the immediately preceding version. In case of disappearance of objects, should be curobjects.zrw.bak rename this file before leaving ScanNav, otherwise it will be overwritten. It is anyway highly recommended safeguard valuables in a separate file in order for the return in case of problems, the file "curobjects.zrw" only a working file to retrieve objects from a session on the other.
- Attention: the notion of object "protected" described above do not include backup of this object in a separate file, the backup procedure therefore also applies to those objects.
- Quick reminder: The tracks are also included in the file "curobjects.zrw. However, as the case of objects being "progressive", a mechanism for automatic backup of the current trace in a separate file already exists (see documentation for the settings). The generated files are then not used directly by ScanNav ( track is in file curobjects.zrw), but it is possible in case of a problem file to go curobjects.zrw reload manually from the saved files automatically
Association of photos to waypoints: It is now possible to associate a photo to a waypoint. This is done in the properties of the waypoint (field associated picture). The photo appears on the screen when you pass the cursor over the waypoint and "tooltips" are enabled.
- The photo appears with a maximum size. To see it in its original size, just click on it, it will open with the associated Windows application.
- It is possible to link any type of asset in place of a photograph. If this is not an image, it will be well understood by displayed in the tooltip, but by clicking the tooltip, the associated application is launched. Examples:
- "c:\video\sequence.avi": Open Windows Media Player or other application associated with the avi to play the movie "sequence.avi" on the screen
- "http://www.scannav.com": open Internet Explorer on the site ScanNav
- etc...
Grib New Module:
- Taking into account the swell direction, and frequency of the wave when available
- some facilities
such as the possibility of having a single color (see interface must be
understandable)
Other:
- Request for confirmation on stop listening GPS, to avoid false arrest involuntary manipulation.
- Possibility to assign colors to individual routes, tracks and areas of danger
- View menu-> Waypoints / routes / etc. to temporarily hide objects (waypoints, etc..) speeding the display scale for the particular weather
- Improving
the monitoring tool navigation (accessible via
): The waypoints can be sorted by their distance from the current position (before sorting was limited to sorting alphabetically or by distance from the point selected.) This allows to find very quickly the waypoints close to the current position, very useful, for example, after marking man overboard
- New licensing system to move to reinstall Windows (the old licenses are still valid)
- Possibility to ignore the speed and direction given by the GPS, for certain power level at which send wrong information. When these options are checked (tab "gps" preferences, ScanNav itself calculates values based on the positions and dates. It is important in this case to give a significant value interpolation (about 40m)
- Flash danger zone when they are on alert (before they changed color)
- Info bubbles trace: display all stored information (winds, probe, etc.)
- Cards Support Maptech BSB 5.0
- Some ergonomic issues and fixes small problems.
