重大工程GIS二次开发的关键技术问题

KEY TECHNICAL PROBLEM ABOUT SECOND DEVELOPMENT OF GIS IN MAJOR PROJECT

本文以 MAPGIS 为例简要介绍了 GIS 系统二次开发中的关键性问题,根据工程实际需要,从开发工具、组件开发、数字制图及数据管理等几个方面对GIS 系统二次开发问题进行了研究,并以研究成果为基础建立重大工程地下环境信息系统,并应用于东深供水改造工程当中,取得了良好效果。

In this paper,the key question about second development of GIS is discussed,which take example for MAPGIS.According to the project practice,it learned the methods and techniques from choosing development tools, groupware exploiture,digital protraction and data management.The result of research is the base of Underground Environment Information System(UEIS)of Important project which is applied in Dong-Shen Water Supply improvement project and achieved nicer effect.
