It is of important significance to use remoe sensing image directly in computer aided cartography. In order to convert remote sensing image data into cartographic data

we must carry out cartographic generalization beforehand.This paper describes in detail a new way of automatic cartographic generalization in microcomputer. With this method

cartographer can control cartographic generalization level conveniently and freely. Once the cartographic generalization level is determined

the machine then completes other work automaticlly.
