D51 Compiled landslide hazard map in GIS database – ACRI-ST
Using MapInfo software, we performed a first version of a Geological/Geographic Information System database for the area of La Clapière Landslide. To date, this consists of:
§ a Digital Elevation Model (DEM) based on aerial photo interpretation (vertical resolution: 1m), covering La Clapière landslide, in grid format;
§ an ortho-photo image in raster format covering La Clapière lanslide zone at a scale of 0.5 meters per pixel with toponymy, road network and hydrography in raster format;
§ the seismic zonage covering the PACA region (south east of France);
§ fault mapping (faults, thrusts…);
§ geological units;
§ hydrological informations (springs, streams and areas of oozing);
§ landslide area.
Hydrogeological informations on La Clapière landslide having contributed to the realization of the SIG come from a map furnished by Yves Guglielmi (now at CNRS-GA)
