摘要
研究利用DEM数据对森林资源规划设计调查的小班地形因子进行求算的过程与方法,自动计算的结果符合国家林业局"森林资源规划设计调查主要技术规定"要求;研究结果表明,利用DEM数据进行小班地形因子的自动求算,可以减少工作量,提高工作效率并能保证精度。
This paper mainly deals with the process and method in eomputating 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.
