- 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 is supported in ScanNav, starting from version 15.0, providing the usage of the Actisense NGT-1 NMEA 2000 adapter.
From version 21.0, the iKonvert and NavLink2 adapters from Digital Yacht also allow the native Nmea 2000 data to be interpreted through the encapsulation in the $PDGY sentence.
To configure the connection, go to the ScanNav preferences, "GPS" tab (or "Instruments" if it is a secondary connection).
- For Actisense: Choose model "Actisense NGT1 NMEA 2000 adapter"
- For Digital Yacht iKonvert or NavLink2: Choose model "Nmea 183 Generic"
can mix the usage of both NMEA 183 and NMEA 2000 instruments
together. The setting in the Instruments tab is similar, choose the
procol "Actisense NGT1 NMEA 2000 adapter" or "NMEA 183" depending on
the target instrument. If information from a single source (for example
wind indicator) arrive on both the NMEA 2000 and NMEA 183 buses, NMEA
183 will be ignored. With the exception of the GPS, for which the
source is always the one declared in the GPS tab, whether it
is NMEA 2000 or 183. All information coming from the GPS is ignored
when it arrives on a port declared in the Instruments tab.
To date, NMEA 2000 is only supported in input. Interface to the pilot or other displays etc... must still be done in NMEA 183.
The list of "PGN" (NMEA 2000 packets) supported by ScanNav from version 15.0 are the following:
- 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
AIS related PGNs:
- 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, and it is possible to set up additional ones. 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 "Track Analysis and Sensors" for more details on taking into account as repeaters and / or logging in the track for analysis.
Note: the 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.
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:
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:
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 18.104.22.168 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"
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.
- Improvements on the Grib download interface

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
- 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
Starting from version 14.0
the GRIB module supports Ocean Current data provided in grib files. The
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 InterfaceThe 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.
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 button to display a menu with following choices:
- "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.
- 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
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
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.
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:
Improvements of performance on display of transparent layers of Grib and currents modules.
New features in version 15.3:
Version 15.3 currents module now supports GRIB files with different depth levels and Stokes Drift (refer to Wikipedia https://en.wikipedia.org/wiki/Stokes_drift). The choice of Depth level and data type is done in the same manner as in the GRIB module (see previous chapter).
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.
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.
- Deletion of individual points from a track / routes / areas: while pressing the <Shift> keyboard key, click on a waypoint, area, or track to delete it.
- Enlarging / Reducing: while pressing the <alt> and <shift> keyboard keys, click on the object to enlarge / shrink, then move the mouse towards the center to shrink, or out to enlarge, before releasing the mouse
- Rotation: while pressing the <alt> and <ctrl> keyboard keys, click on the object to rotate, then move the mouse to choose the angle, before releasing the mouse
- The only possible operation on tracks is to delete a point, other operations having no meaning (please contact us if you have any needs in this regard)
- For move, scale, and rotate operations, if a selection is active and you click on a selected object, the operation applies to all selected objects (except read-only objects, and tracks)
- Shortcut: You can move / enlarge / shrink / rotate an object as described above without having to select the "transform" tool, Just press the <alt> keyboard key, regardless of the currently selected tool
- 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...)
- This new option allows you to see on the
screen a circle of variable diameter depending on the available map
scale and zoom, can represent a safety margin, commonly called "Rule of
thumb". See article on SHOM The precautions for use
on the GPS which reads in part:
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 cards 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:
- General MOB system enhancements with dead-reckoning of the MOB position according to a given drift.
|When a MOB condition is raised, either
automatically by the NKE
system (or any other compatible system), or manually with the MOB
function integrated in ScanNav, a Waypoint is created on the current
position, and the MOB window is 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 in pdf format.
The new tool can create lines increases. Click on the map on the bitter, and move the cursor while the mouse button and release at the end of the line rehabilitation.
The dialog box below allows you to refine against the settings and set the display settings, such as the type and thickness of the line and color.
You can also click on the item and release it immediately, then set the angle of recovery and the length of the segment (in nautical miles). In this case, the values are initialized to recovery against the ship's position
The display of the angle can increase êtreaffiché in true or magnetic and / or reversed with the choice "relevant" or "Inverse Rel"
It is also possible to reverse the increase through the "Reverse", ie the end of the line becomes a point of recovery.
You can then modify a recovery by opening its properties box, or by using the tool changes:
|Note: In addition to its utility display complementary to the card, the recovery tool can be used to provide help to train to make triangulations to position ...|
|Note for users of previous versions: the button without doubt will be missing from the tool-bar. To make it appear, you must reset the tool-bar via the menu "View" => "Reset tools", or clicking the right mouse button on the tool-bar and selecting "Reset" or "customize" (see the documentation for the customization of tool-bars)|
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.
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
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
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.
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:
|Choose the Heading among:
- "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 can both be parameterized in length by time or distance, and in different units by selecting the corresponding options.
New feature in version 15.0:A new more standard scale chooser replaces the existing one by default.
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.
Use this button to fill the different fields with values corresponding to the present view displayed in ScanNav
Use this button to create a waypoint at the position defined in the fields
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 road 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 road from an existing route, click on the road with the right mouse button (on the maps or in the list of objects), and choose the "Clone the road"
|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
Starting from version 14.0 a new display is available, giving ETE and ETA for all waypoints in the active route, together with other route information. To activate, use menu "Displays"==> "Route followup".
Several information are available in separate columns. They can be configured by right-clicking in the window to open the contextual menu and choosing the "Columns configuration" entry.
ETA : Estimated Time of Arrival (the date is also indicated above
- ETE : Estimated Time Enroute for each individual route segment.
- ETE accumulated: Estimated Time Enroute to waypoint starting from the current position
- Distance: Distance in Nautical miles of each individual route segment
- Speed: Estimated speed (VMG) for each individual route segment .
- COG: Course Over Ground to follow for each segment.
The first line corresponds to the present destination waypoint. Speed and ETE/ETA are deducted from the instant VMG to the waypoint (values should be identical to the individual ETE/ETA Displays)
Estimated values for the following waypoints can be calculated according different methods to choose between the following using the contextual menu:
- Route values:
Fixed speed for each segment, defined in the route properties (refer to
the chapter Routes further in
- Constant VMG: The speed is set to the current VMG for all segments (route properties are ignored).
- VMG+Route combined: The speed given in the route properties for each segment is combined with the present VMG,. For example, if the speed defined in the route for the current segment is 8 knots, but he current VMG is only 4 knots, a ratio of 1/2 will be applied to estimated speeds for the following segments compared to their definition in the route properties.
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.
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
- 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:
Settings can be changed in the "Other" tab of the preferences. Three different fonts can be customized (subject to change for more individual settings in later versions):
each type, you may choose the font type, size, and attributes (Bold /
Italic / Underlined)
"Default Values" let you revert to factory settings.
The 3 types are used in the following contexts: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) Navionics charts text size:
customize the size of text
displayed inside Navionics charts in the "Navionics preferences" window
(accessible through the "File" menu) providing a new "Text Scale"
ruler, that lets you apply a global scale factor to the size
all text features (sounds, names, etc...)
Note: to grow icons sizes, use one of the "Easy View" display settings.
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.
- 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 "Active layer" defines the default class that will be assigned to any newly created object. It's choice can be made by selecting an existing item in the list (click on the arrow to the right of the field, or double-click on an element of the list), or by entering a new name. If the layer does not exist yet, it will be created as soon as a new object is created and automatically assigned to this class.
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.
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,
(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.
- GPX exchange Format support: GPX is an exchange format for waypoints, routes, tracks, etc. ... which is supported by a growing number of software and plotters, and allows interoperability between different systems. 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.
- Support for latest Garmin USB
- And for connected GPS RS232, Garmin protocol support in monitoring real-time navigation (avoids having to change the protocol on the GPS when it changes from monitoring real-time transfer mode, and vice versa)
- There are now three choices in the GPS tab of
preferences for Garmin GPS:
- Garmin - NMEA: corresponds to the old mode (RS232 (COM port), followed by NMEA and Garmin transfer mode)
- Garmin - GRMN (RS232): always via a COM port, but the protocol of the GPS should be set to Garmin / Garmin
- Garmin - USB: the new Garmin gps connected USB
- Partial implementation for the transfer of waypoints and routes to the GPS FURUNO.
- Taking into account the
magnetic heading in VTG NMEA sentence:
(when the cap is not true)
- did earlier in the course that's true, but some apparently do configs that the magnetic heading
- WORKAROUND Girouette new problem that NASA provided a bad checksum:
- - Checked: as before, there must have a valid checksum in NMEA frames
- Marked in gray: the former as "unchecked" accepts all sentences without checksum, but if a checksum is valid it must be
- Unchecked: this mode should be used only when an instrument sending invalid checksums. These are ignored in this case.
- - Checked: as before, there must have a valid checksum in NMEA frames
- Direct import of waypoints wrecks wrecks of cdrom SHOM (via File menu)
- 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 windowModifications 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 margins are
given in proportion to the screen. By specifying 1/4 (or 0.25), ScanNav
calculates a quarter of the screen in addition on each side of the
screen, allowing you to pan smoothly. On powerful configurations, it
can be advantageous to increase this value up to a maximum of 1/1 (or
1) (the equivalent of 9 screens). On a small configuration, you can
decrease it to 0 if you notice a long delay after scrolling or zooming.
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
| When you click the map to set a georeferencing, behavior depending on
the choice among the 3 values:
Please refer to the main documentation for other functions
points Google" 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
with their geo Latitude / Longitude initialized around the last area
requested Google Earth (with F11).
Their position on the image being spread broadly across the screen.
This allows you to quickly reference a screenshot Google, it only remains to reposition the four points on the image, taking care to select the "Move Point" not to change the longitude / latitude
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.
A new tab preferences "NMEA" creates multiple outputs and set the sentences to be sent to the driver or repeater (see the documentation for the driver / repeater for phrases supported by it, more details will be given later)
- The actual output is activated with the new button the tool-bar
- For ScanNav send valid information to the pilot must control navigation ( ) And the GPS is active listening
- 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
- 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.
Jpeg format and PNG format for entry into
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.
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.
- 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
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
- 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.
