【摘要】 首先介绍了WMS(网络地图服务)的基本概念,接着简单的说明了空间数据共享方法的发展情况,重点突出了GML的优势。基于GML的WMS能够为Web环境下的空间数据互操作技术和空间信息处理互操作技术提供简单而又有效的基本数据访问、地图显示和简单的数据位置查询。该文最后给出了以MapGIS平台为基础的基于GML的WMS的体系结构和实现方法。更多还原

【Abstract】 The basic definition of WMS(Web Map Services) was introduced, and then the technique development of sharing spatial data on network was illuminated briefly, which concentrated on predominance of GML(Geographic Markup Language). WMS, based on GML, were able to support easily and effectively the interfaces of essential data access, map display and straightforward inquire about position and location for spatial data interoperability technology and spatial information management technology. Finally a set of WMS architecture and implementation method based on GML, running on MapGIS platform were put forward.更多还原
