基于WEB GIS的网上地图发布系统

为配合数字国土和新一论国土资源大调查工作及充分开发利用图书馆的地图资源,设计开发了基于万维网地理信息系统WebGIS(Web Geographical Information System)的网上地图发布系统.该系统以Autodesk公司的万维网地理信息系统解决方案(MapGuide)为基础平台, 充分利用其快速强大的图形发布处理能力,采用扩展标示语言XML(Extensible Markup Language)技术构建用户交互查询服务及动态地图发布服务,实现地质图件的科学管理和快速高效的数据发布服务.系统不仅能够对大量的空间图形数据进行查询与维护,还能够对数据进行分析,利用直观的空间概念达到方便、快捷的分析管理地图的目的.实际应用证明,该系统在数据统一管理、无缝连接、索引机制、开放式结构、存储及开发标准等方面具有很大的优势和发展空间.

WEB GIS-based mapping web distribution system

Close cooperating in carrying out digital land and a new round of surveys of land and resources,fully utilizing geo-map in national geological library of china,a WebGIS-based mapping distribution system based on the MapGuide software is built,it is the Internet GIS solution of Autodesk company. This system includes the client interactive query on the browser-side and active mapping services on the server-side with XML technology.It efficiently utilizes the MapGuide's attributes, such as the prompt GIS mapping web distributing and processing activities. And it queries and administrates spatial data fast, and conveniently analyzes the data with the intuitionistic space concept. The practical application shows that the system has the advantage and good future development at following aspects:data management, seamless connection, index mechanism, open structure, storage and exploitation criterion,etc.
