基于ArcView的等高线批赋值

Automatically assigning elevation value on topographic map in ArcView

等高线是地形表达最为常用的形式,它是地理信息系统基础的数据模型。高程是构成等高线的重要属性。为了在ArcView中利用矢量化法生成等高线时,实现对等高线批量赋予高程值,提高等高线高程输入的效率和准确度,用Avenue编程实现了ArcView的等高线批赋值功能。本文首先介绍了批赋值的基本思想,然后结合Avenue关键代码,具体从赋值等高线的获取与排序、等高线属性的获取与赋值等方面,阐述了ArcView中实现等高线批赋值的思路。

In order to realize assigning elevation value on topographic map in ArcView efficiently.This paper proposed a method using Avenue to realize assigning elevation value automatically.The contour line is the most commonly method of expressing the terrain and it is one of the foundation data model of Geographic Information System.The elevation is the important attribute of the contour line.This article firstly made simple introduction to Avenue,then introduced the basic thought of how to automatically assign elevation value in ArcView.
