| Abstract: | Topographic symbol is an important component of topographic map.Taking what method to realize automatic plotting of topographic symbol is the key to develop the digital surveying and mapping software.This article classifies the topographic symbols by analyzing their features.On this foundation,it develops AutoCAD for the second time with Visual LISP,and implements plotting of topographical symbols. |
