Abstract
During the MapGIS software processing the geological map without base data, there is great dififculty in the late utilization stage, for example the accuracy is not enough, and drawing speed is slow. This paper summarizes an effective method of transferring contour map into numerical value which is so convenient for post-data analysis. To take an “average subsidence rate map within 5 years” as an example, that is required in geological hazard assessment work, this paper shows the detailed converting processes from the contour map to numerical value.关键词
