摘要

摘要: 目的从地图综合经典决策模式出发,提出了“算子、算法、参量”的三层决策模式与WPS交互流程之间的隐性对应关系,并由此扩展到通用的服务链创建;然后,利用这种对应关系梳理了服务语义增强必需的4类语义描述信息;最后,使用该信息扩展了WPS规范。该方法归纳的语义信息简洁精确,可分层次嵌入WPS服务的交互流程,在顾及标准的同时提升了地图综合服务的语义互操作能力。

Abstract: Objective Web service and map generalization can improve syntactic and semantic interoperability how-ever their collaboration remains unsolved.On the one hand,standards for geospatial information serv-ices are generic and do not consider the specific field,such as map generalization;on the other hand,the generalization of knowledge is too complex to systematically extract accurate information to enrichthe semantics of a map generalization service.This paper aims to investigate the classical“operator-al-gorithm-threshold”decision mode,introducing an implicit correspondence between the mode and WPSinteraction process,and further extending this to service chaining.Based on this implicit relationship,four kinds of information suitable for enriching generalization services are summarized and analyzed indetail.Finally,this semantic information mentioned above is used to extend the WPS specification.The semantic information in this study is concise and accurate enough to be embedded in the WPS in-teraction process hierarchically and thus improves the semantic interoperability of a map generalizationservice while taking the OGC standard into account.
