摘要
在利用不规则排列的采样数据建立DEM时,通常可采用平面三角网络拟合地表形态,这种拟合不可避免地会出现一定程度的失真。本文推导了对失真进行补偿的修正公式。该公式原理简单,计算方便,经过试验,具有很好的补偿效益。
: When sampling data of irregular arrangement are used in the esta-
blishment of DEM, landforms can generally be fitted by using plane triangular
mesh. Such a fitting would unavoidably lead to some distortion. In order to comp-
eusate this distortion, revised formulas are derived in this paper. They have the
advantage of being simple in principle and convenient for computation. The compe-
nsating efficiency has been validated by experiments.
