Web客户端地理空间数据推送模型研究

The Web Client Geospatial Data Push Model Research

设计一个基于Web客户端的地理空间信息推送模型,该模型支持多用户实时协同标绘,无缝地推送数据,实现了基于网络平台的地理空间信息的交流和感知。该模型利用网站开发技术、数据库管理技术、地图服务技术以及信息推送技术实现了将远程客户端发送的地理空间数据直接推送更新到用户浏览器的页面中,实现地图页面的局部更新,并考虑了推送失效的处理办法。

The Web-based client geospatial information push model supports multi -user real-time collaborative plotting , seamless push data , implements the geospatial information based on network platform of communication and perception ; The model using the Website development technology , database management technology , map services and information push technology to realize the re-mote client sends the geographical spatial data updating directly to the user＆#39;s browser map page , realizing the part update of the Web map page , and considering the push failure treatment method .
