| Abstract: | This paper mainly deals with the process and method in computating the site factors in forest resources investigation with the help of DEM data in GIS.The study showed that the result of auto-computation meets well the demand of the principle of main techniques of forest resources investigation.This study also showed that the work load can be greatly decreased and the precision can be highly assured by using DEM data to computing the sub-compartment site factors. |
