Spatial Analysis of Multi-Source Data and Its Application in Motuo, Tibet

This paper presents a spatial analysis method based on multi-temporal DEM elevation changes and DOM images changes and gives a qualitative and quantitative analysis of the terrain change. It has been applied in Mutuo of Tibet where the terrain and geological are very complex and the action of the earth's surface is active, and proved to be a quick, effective and precise method for analyzing the stability of the terrain.
