Study on the Method of Generating Digital Elevation Topographic Map in the MATLAB

Article Preview

Abstract:

The modern 2d digital topographic map can not meet the people to the 3d information needs.This paper analyzes the AutoCAD graphics file format.Use of MATLAB platform,designed the interface of the program based on the data extracted from DXF file,and extract valid data. Apply this method to extract terrain data of the contour to establish 3d geological model which has obtained a better effect. And solve the AutoCAD system and MATLAB data sharing between effectively.Use of the powerful graphics features of MATLAB, we have put forward a new way for 3d geological modeling and generation DEM.
