| 摘 要： | 在土方量的计算中，需要提取点的3维坐标。而许多电子版地形图的z坐标值均为0，此时就需要对关联点的z坐标赋高程注记值。本文介绍用AutoLisp进行简单的编程、实现赋值的过程。

| Abstract: | To Calculate the value of earthwork,it is necessary to obtain three -dimensional coordinates. But the value of z- coordinates is zero in some electronic map,it is necessary to change z- coordinates value of a point into the value by the nearest note. The auther introduces a simple programme to realize it. |
