| 摘 要： | The application of Digital Elevation Model (DEM) is drawing more and more attention.Different ways to set up DEM are being tested in line with various local conditions.This paper describes the experiment of setting up DEM on the basis of scanned raster data from separations of contour lines after the pre-processing of the contour image and the running of a program on a microcomputer.The software is designed to simulate the intelligent activities of human experts in evaluating the point elevation for the DEM.
