Information System of Land Utilization Based on Google Maps

目前常见的Web地图服务仅支持浏览和查询,不支持矢量数据的发布。文章提出一种基于Google Maps的WebGIS构建方法,支持多种浏览器的矢量数据互操作及空间分析。针对郑州市土地利用信息发布需求,采用B/S架构,借助Google Maps API和AJAX技术,实现了土地利用信息系统化,标准化发布平台。该平台响应速度快,面向多种用户,支持数据共享,能更好的为土地利用变化研究及土地整理决策提供服务。

Typical Web map services of current only supports functions of browsing and querying,and does not support the distribute of the vector data.A WebGIS construction method based on the Google Maps was proposed in this paper.It supports vector data processing in variety of client browser,which has good interoperability and ability of spatial analysis.Aiming at the requirement for land usage information distribution of Zhengzhou City,a systematic and standardized platform which based on B/S architecture has been developed adopting the technology of Google Maps API and AJAX.The platform responses fast and supports for mass data sharing,which provided friendly interface face to variety of users.It also can provide information services for land use change research and land consolidation planning.
