基于WEB的用户服务与信息发布分系统设计与实现

DESIGN OF USER SERVICE AND INFORMATION DISTRIBUTION SUB-SYSTEM BASED ON WEB SERVICE AND ITS IMPLEMENTATION

用户服务与信息发布分系统是地质勘查遥感系统的重要分系统之一。分系统主要面向地质调查和项目管理人员,以层次化、组件式思想设计开发,并充分考虑了系统的可扩展性。采用B/S模式,通过Web GIS发布技术、卫星遥感产品多维可视化发布技术、基于工作流控制的WEB信息发布、客户服务等,直接进行地图数据、海量遥感影像数据和专题产品数据的快速检索、显示和下载,分系统在试运行中取得了良好的应用效果。

User Service and Information Distribution Sub-system is one of the most important sub-systems of Remote Sensing Processing Systems. The sub-system, which is designed by hierarchical and component type conception and is fully considered its extendibility,is mainly used for staff of geological exploration and project management. Based on WEB information distribution and user service, The B / S Model is applied with distribution technology of Web GIS and multidimensional visualization of remote sensing image. The sub-system can achieve instantly searching,displaying and downloading of map data,mass remote sensing data and thematic product data. It has achieved good application effects in trial running.
