农田WebGIS服务系统设计和开发

基于MapXtreme组件构建了服务器端农田WebGIS服务系统。该平台提供WebGIS服务器与移动终端之间的数据交换服务,并利用Internet发布、接收和处理农田信息,提供农田生产决策支持。用户使用客户端浏览器就可以对农田信息进行浏览、查询、分析,并获取农田决策。通过该系统,农田管理者可以使用PDA通过GPRS将实时收集到的农田GIS信息(采样位置及该位置的土壤水分,土壤温度等)传输到WebGIS服务器上;服务器则远程收集农田实时信息进行分析计算,并根据分析计算结果进行农田生产决策,从而真正实现农田最优化管理。系统试运行表明,利用MapXtreme组件提供的WebGIS功能,实现了高效的农田GIS Web化管理。

Design and Development of Farmland WebGIS Service System

A farmland WebGIS service system working on server side was developed based on MapXtreme component.The platform can provide data exchange services between WebGIS server and mobile or desktop terminal,and it can release farming information,receive farming data,manage and process farmland data and provide farming production support decisions.Users can use this system to carry out farming management such as browsing and inquiring farming information,analyzing farmland data,or acquiring farming production decisions.And all of these works can be done via a browser installed at client-side.By using this system,farmers can collect farming GIS information(the GPS data of sampling points and their features such as soil moisture,soil temperature,etc) collected from farmland and uploaded to the WebGIS server by a farming PDA.At the same time,the farmland WebGIS server receives farming information from farming PDA via telecommunication,and then analyzes and computes farming data,finally provide the decision making according to the analysis results for farmers.Consequently it can lead to optimal farming management.System commissioning shows that farmland Web and GIS management can be fulfilled efficiently with the WebGIS component of MapXtreme.
