摘要:

采用Browser/Server系统架构,使用ArcIMS作为网络地图发布平台,结合先进的ASP技术,开发网络湖泊数据库,实现湖泊信息资源的共享。湖泊信息资源包括湖泊的物理、化学、生物特性,以及湖泊的地图、遥感影像和风景照片等。基于WebGIS的湖泊信息系统,其功能有湖泊数据库的基本管理功能和基本空间分析功能,它们主要是空间与属性数据的编辑与更新,信息的检索与查询,矢量数据的显示、缩放、漫游,缓冲区分析,以及专题图制作等。

关键词: 湖泊, 数据库, WebGIS, 信息共享

Abstract:

In order to realize the target sharing of lake information resources, Browser/Server framework was adopted, ArcIMS acted as publisher of maps on internet, advanced ASP technique combined, and lake database on internet developed. Lake information resources include physical, chemical and biological characteristics of lakes, as well as maps, remote sensing images, scenery pictures, etc. There are basic management and spatial analysis functions to lake database in the lake information system based on WebGIS. They are mainly: editing and updating spatial and none-spatial data, searching and inquiring information, displaying, zooming in, zooming out, and roaming of vector data, buffer analyzing and thematic mapping, and so on.

Key words: lake, database, WebGIS, information sharing
