微机地理信息系统上图形编辑系统的设计与实现

Design and Realization of Graphic Editing System in Micro-Computer Based GIS

图形编辑系统是地理信息系统图形工作站上必不可少的一个组成部分,它对地理信息的获取,更新及其它处理都是至关重要的。在本文中,作者阐述了在微机地理信息系统上实现图形编辑系统时,地图数据的组织结构、系统的实现环境和交互设备等方面应具备的必要前提,并介绍了一个基于微机实现的系统设计。

Graphic editing system is an indispensable component of graphic work station in micro-computer based Geographic Information System, which is most important for the capturing, updating and other handling of geographic data. In this paper, the author describes the prerequisites to realize a graphic editing system on the organization and structurization of cartographic data, necessary environment and interactive devices for graphic editing, etc, and introduces the system design which has been realized on micro-computer.
