【摘要】：随着海量分布式地理空间数据的持续增长和地理空间处理服务复杂程度的不断增加,异步地理空间信息服务已经成为当前地理空间信息领域的研究热点。开放地理信息联盟(Open GIS Consortium,OGC)针对地理空间信息服务互操作制定的一系列标准规范大多建立在同步协议之上,适用于较为简单的非实时计算环境,难以满足复杂、动态的异步信息处理需求。本文提出了一种异步网络处理服务实现方法,以网络处理服务(Web processing service,WPS)和网络通知服务(Web notification service,WNS)为核心,扩展了标准的网络处理服务请求,从而支持异步调用。
[Abstract]:With the continuous growth of massive distributed geospatial data and the increasing complexity of geospatial processing services asynchronous geospatial information services have become the current research hotspot in the field of geospatial information. A series of standards and specifications for interoperability of geospatial information services developed by Open GIS Consortium (OGC) are mostly based on synchronous protocols, which are suitable for simple non-real-time computing environments and are difficult to meet the complexity. Dynamic asynchronous information processing requirements. In this paper, an asynchronous network processing service implementation method is proposed, which extends the standard network processing service request by using the network processing service WPSs and the network notification service web notification service WNSs as the core, so as to support asynchronous invocation.
