摘要: 面向空间数据处理的服务描述、部署、发现、调用过程是空间数据服务化处理的关键问题,直接关系到空间分析与相关数据处理计算的实现方式和执行效率。在标准网络服务模式之上,参照OGC规范设计空间数据网络过程处理服务的实现模型。并在空间数据分析和网络处理服务模型基础上,对网络服务的资源结构、服务调用模式、空间分析函数、数据处理流程等部分给出设计和定义。并以空间缓冲区分析算法为实例,实现过程处理服务模型实例,并给出分布式网络环境下空间数据处理服务的发布、调用与计算模式的完整实现方法。

关键词: 空间分析, 过程处理服务, 服务发布与调用, 地理信息系统

Abstract: The description,creation,deployment,accessing and invoking of services are important research steps in geospatial data analysis under distributed Internet environment.The approach directly affects the design and implementation of spatial analysis algorithm and geospatial data processing service.Spatial analysis oriented Web processing service model has been put forward in distributed Internet environment,bringing strict requirements to service resource description,spatial analysis algorithm and geospatial data processing.Finally,based on the processing service model,a specific spatial analysis implementation as well as some improvements has been achieved for the service deployment and invoking.

Key words: spatial analysis, processing service, Web service deployment and invoking, Geographic Information System(GIS)
