SCAN Littoral®
The product SCAN Littoral® is a collection of continuous colour digital map images of the coast, obtained via georeferenced assembling with grid squares of raster data from Shom nautical charts and IGN 1:25,000 land maps. The SCAN Littoral® solution includes a series of digital images with no additions, legends or georeferencing information.

- Supplemental Information
-
SCAN Littoral® breaks down into several sub-sections: - SCAN Littoral® Topographical, which excludes any tourist information, - SCAN Littoral® Tourism which is identical to SCAN Littoral® Topographical, but shows tourist information (exhaustive information is added to the Top25 map grid squares and partial information is added to GR for Blue series map zones only).

The sea floor: The sea map base layer is an image of printed nautical charts, contoured by the frame and the coast line. 1:50,000 charts are generally used for the mainland France coast. 1:20,000 charts are also used for estuaries, bays and gulfs and two 1:150,000 charts are used along the Aquitaine coast. 1:50,000 charts will be used for Reunion island, Martinique and Guadeloupe. 1:300,000 charts will be completed by detailed 1:50,000 charts for French Guiana. Assembly tables for maps to be incorporated in the SCAN Littoral® solution can be found in Appendix B.
Land maps: The land map is an image version of the IGN map (raster data from 1: 25,000) contoured at the same coast line, except coastal toponymy, which may appear at sea. The coast line Coast line data (for the highest tide with a tidal coefficient of 120 and in normal weather conditions) were obtained from the HistoLitt® database. These data were prepared jointly by Shom and IGN. Shom larger scale charts were converted to digital format for the required geographic scope (from 1: 5,000 to 1: 50,000 or even 1: 150,000), and updated using the IGN ORTHO® database. This line is now used to match terrestrial data and marine data for our reference materials. On the other hand, this coast line is not defined for the entire length of the French Guyanese coast due to clouds on airborne photographs. Pending the definition of this coast line, the French Guyanese map was compiled using digitally converted terrestrial and marine maps. The technical specifications for the French Guyanese solution are therefore slightly different.
