摘要
利用Web服务和Agent特性来解决空间信息GIS领域的动态服务问题。提出了基于Web和Agent的GIS动态服务模型,阐述了动态服务原理和相关的实现技术,特别是利用创建、迁移GISAgent和构件下载策略,以及GISAgent和Web服务的交互操作和集成技术,实现了用功能构件的移动代替海量空间数据的移动,提高了分布式网络的计算速度,改进了空间数据处理的瓶颈问题。
Web Services and Agent are applied to solve dynamic service problems in GIS. GIS dynamic services model based on Web and Agent is introduced. The principle and the implementation technology of dynamic service are expatiated, especially creation and transfer of GISAgent ,components loading, interaction and integration between GISAgent and Web Services. The transfer-of functional components is substituted for the transfer of a great deal of spatial data. The computing speed in distributed network is enhanced, and the bottleneck in spatial data processing is solved.
