| Abstract: | Using 2-D and 3-D multi satellite data (SPOT and LANDSAT TM) in a GIS allows us to produce 3-D digital elevation maps (DEM)
through the techniques of remote sensing (RS) analysis and computer aided mapping. In the field of geotechnical research,
since 1992, some works have been made in cooperation with ICIMOD-MENRIS, the department of Mines and Geology in Nepal, and
the bilateral cooperation from both France and Germany. The use of 2-D and 3-D digital maps to geological and geotechnical
research and risks analysis, concerns here the evaluation of the new water supply project Kathmandu-Melamchi proposed by WHO-UNDP
and the World Bank.
