针对协同会商服务的特点,采用J2EE技术体系搭建开源WebGIS服务平台.从WebGIS开源技术出发,分析设计系统的架构、应用模式,并对其中的基于5层15级的瓦片结构设计和地图瓦片在OpenLayers中的加载等技术难点进行研究,进而实现会商中的群组管理、信息展示以及会话管理三大核心,从而达到遥感会商的目的.

英文摘要：

According to the characteristics of collaborative consultation service, use J2EE technology to build the system of open source WebGIS service platform. Starting with the open source WebGIS technology and analyze ar- chitecture and usage patterns of system designed, and then resolve technical difficulties, such as the design of structure based on five-layer fifteen-level tile and map tiles in the Openlayers loading and others to overcome, so as to realize three cores： group management, information display and session management, and achieve the purpose of remote consultation.
