Cartographic and Navigation software assisted by GPS

ScanNav lets you build your own digital maps from your paper charts. A simple desktop scanner is sufficient, the charts workshop integrated in ScanNav will do the stitching of the different scanned pieces, and the georeferencement of the result in latitude/longitude.

You can also use the charts workshop to correct existing charts so as to have up to date charts and navigate safely

You can of course also use commercial electronic charts sold on CD ROM. ScanNav is compatible with most common RASTER chart formats (BSB, Maptech, Softcharts, etc...)
Vector charts in S57 format are supported in ScanNav from release 5.5

At home, examine your maps in all their details, and determine your next holidays cruise. Create waypoints, routes, calculate bearings and distances, determine your stops... ScanNav gives you all the necessary drawing and calculation tools to prepare you to the best for your trip.

If you do not wish to bring your PC on board, you will be able with a single click to transfer your prepared waypoints and routes to most existing GPS

ScanNav and the Guide Méditerranée are interfaced so you can consult the guide by clicking on the chart in ScanNav, or position ScanNav at the corresponding location on the chart directly from the guide's web page.

Ready to Navigate

On your boat, connect your GPS to your PC, and you will see your boat moving on the chart in real time, with an immediate estimation of where you will be in a certain time using the heading line graduated in time periods. You also have access to all navigation parameters, such as heading, speed, remaining distance, estimated arrival time, etc...

You can also view (and memorize) any other instruments such as the sound, wind indicator, compass, loch in adapted repeaters. All calculated information may also be output to external NMEA displays, and you can interface the auto-pilot.

You can choose to follow a previously created route, or navigate to a single waypoint, alarms will warn you of any cross track error, arrival on waypoints, proximity of danger areas... You can mark instant waypoints such as MOB, fishing spots, anchor areas, or any other events. You can also associate photographs to waypoints.

"Seamless" management of charts:
You just tell once to ScanNav where your maps are on your disk (or CD-ROM), he will then manage them automatically to show the best fitted chart(s) on screen according to current location and scale level. Several maps may be combined together automatically so as to cover the whole screen, even if at different scales. You will therefore never have a partial blank screen even if navigating on borders of the map.

ScanNav handles tidal information by overlapping tidal currents on your map for any time, according to the hour and amplitudes of tides. It is also interfaced with the WXTide third party software to show heights of tides.

The data to calculate currents are originated from the SHOM (authorization n° 30/2005).

Click here for details on available currents areas. In this version, only French coasts (Including the Channel) are available.

Using standard GRIB files ScanNav lets you overlay weather forecasts ( Wind, pressure, swell, precipitations, temperatures) directly on your map. GRIB files can be downloaded using regular cell phones when in covered area, or using satellite or BLU (emission/reception) connections when in the great blue.

World scale (grid step around 50nm) GRIB files originated from the Noaa can be downloaded free.

MétéoGrib Offer:

In cooperation with METEOREM, we propose affordable subscriptions for high resolution grib files (around 8NM grid step)

ScanNav keeps track of every information issued from your GPS or other connected instruments, and therefore gives you a graphical journal, letting you analyze your trip in all its details (doesn't substitute to the obligatory legal paper journal)

If you didn't bring your pc onboard or if it was off during navigation, you still can after your trip download tracks from most current gps, so as to visualize and analyze them in ScanNav.

With the MrSid file format support, you can use aerial photographs of the French coasts, or satellite photographs (world coverage), both available free on Internet. Although not real navigation maps, they constitute a good additional navigation aid, as they are very precise, and give you another vision of the coasts and nature of the bottom.

A library of waypoints associated to oblique photographic views of most harbors and splits of France is also provided free of charge (origin SHOM, precision 1 minute of arc)

ScanNav also supports UTM and Lambert projections and is therefore also adapted for terrestrial cartography and use (excursion, mountain bike, car, agriculture, ...)
