基于WEBGIS技术的地质数据库信息系统开发及其实现

Development and realization of an information system for geological data based on WEBGIS

讨论了 WEBGIS技术的理论及其实现方法 ,并且通过 ASP、组件技术在国产 GIS平台 MAPGIS基础之上实现了地质数据库发布系统 .系统采用 3层体系结构 ,完成了地质数据库基于互联网的检索、分幅查询、分省查询、属性查询以及图形下载等功能 ,并达到了较好的效果 .

This paper discusses several kinds of resolving plan for WEBGIS.It also gives a realization of information system for geological data using ASP,components technology and MAPGIS platform.The system adopts the three-tier architecture,providing the function of querying and analyzing on spatial data and attributing data of geological data based on Internet.All of these give the administration section effective and scientific decision support.
