A 5 m multi-scale topographic position color composite (MTPCC) across France

The multi-scale topographic position color composite (MTPCC) describes the position of a pixel relative to its neighborhood at several spatial scales. It was derived from the national airborne DTM (RGE ALTI ®) at 5 m spatial resolution, which is available from the website of the French National Geographic Institute (IGN) (https://geoservices.ign.fr/). Dataset includes: 280 GeoTIFF raster files (MTPCC_000.tif) projected in the French Lambert-93 system (EPSG code 2154), each file corresponding to a 50 x 50 km tile. The number indicates the tile of interest ; 1 vector tile index at Google Earth format (tile_index.kmz) showing the location of each tile. This file has been created to facilitate download layer only on area of interest. To reduce storage space and download time, each raster file has been packed at 7-Zip freeware format. A complete description of the dataset can be found in Panhelleux, L., Rapinel, S., Lemercier, B., Gayet, G., Hubert-Moy, L., 2023.
