Abstract:DEM (Digital Elevation Model) is the most important basis of the Digital Earth model and other digital models. There are many methods to obtain it. This paper discusses the technique and procedure of DEM extraction by using airphotoes under OEAD platform? An example of DEM extraction for Jinlong Mountain is given, and some problems existent in DEM extraction are discussed.
