摘要
针对当前GIS功能服务薄弱的问题,研究并建立了基于OGC WPS规范的分布式GIS功能服务共享体系,分析了开放的空间数据组织与编码、组件式设计、GML压缩传输策略、基于Multi Agent的分布式请求处理策略等关键技术,构建了多种GIS功能服务共享的应用实验。
The present GIS developments have little focused on providing open and smart processing service,To solve this problem,the paper studies and establishes a distributed map processing service sharing system based on OGC WPS Specification.From thorough analyses of the open spatial data model and encoding,COM design rules,strategy of GML compression transfer and proxy strategy of distributed request based on Multi Agent,the paper designs web and desktop applications to access and share the map processing service and proves the theories and methods proposed in the paper.GIS development and application can be more efficient in every domains by realizing the open and distributed map processing service.
