微机专题制图系统的设计与实现

The Design and Realization of Personal Computer Based Thematic Mapping System

本文提出了微机支持的Auto CAD图形软件工具作为专题图图形管理系统的设想,用链码数据结构存贮多边形,借助高级语言与Auto CAD的软件接口以及Autolisp语言的应用,拓宽了系统的实用性。

In the peper, Auto CAD graphic software used for thematic map database has been proposed. In order to represent polygons, the chain-coding data structure is developed. The interface between advanced languages and Auto CAD with the software is also added. This system has already been used for mapping of some cities.
