摘 要：
本文从地形林相图的网格高程数据矩阵出发,将隐藏线消除问题化为隐藏点的清除问题。并在此基础上定义两类隐藏点。通过三维图象的透视投影变换和与森林资源DBASE数据的联网,可绘制彩色森林立体专业图,并成功地解决了铁路线型库的问题。该系统为森林立体专业图奠定理论依据。

摘 要：
In this article the elimination of the concealed line is transferred to the one of the concealed point from the grid elevation datum matrix of the topographie forest facies. the definition of the two concealed points is given on the basis. On the network of 3-dimensional perspective projcction transforming and the forest resource DBASE data, the color forest stereogram can be drawn. The problem of the railway linear base will succed in being solved. This system will be beneficially uscful for the application of the forest stercograms.
