基于B/S模式的四湖流域土地利用信息系统设计与实现

Design and Implementation of Four Lakes Region Land-using Information System Based on B/S Mode

随着Internet和WebGIS技术的发展,利用浏览器远程访问空间数据库得以实现,系统架构于IIS Web服务器上,通过Arcgis server服务器处理用户GIS数据请求,运用C#语言操纵ArcObjects实现用户查询与分析,GIS数据存储于SQL Server数据库中,遥感数据存储于目录文件中。本系统能动态直观地反映四湖流域土地利用信息的时空分布,提出了基于B/S模式的WebGIS实现方法,降低了开发成本,可以满足普通用户和从事科学研究用户的需求。

With the development of Internet and WEBGIS technology,it has become realized to access to remote spatial database by explorer,and with the system based on IIS WEB server,through Arcgis server user＇s GIS data request was dealt,and the user query and analysis with C# language control ArcObjects were realized,with the GIS data storage in SQL Server database and remote sense data into director.This system can show intuitively dynamically the spatial distribution of four lakes region land-using information,and in this thesis the realization methods of WebGIS based on B/S mode was proposed,to reduce the development cost,and satisfy the normal user and scientific research personnel＇s needs.
