【摘要】：隨著海量分布式地理空間數(shù)據(jù)的持續(xù)增長和地理空間處理服務(wù)復(fù)雜程度的不斷增加,異步地理空間信息服務(wù)已經(jīng)成為當(dāng)前地理空間信息領(lǐng)域的研究熱點(diǎn)。開放地理信息聯(lián)盟(Open GIS Consortium,OGC)針對地理空間信息服務(wù)互操作制定的一系列標(biāo)準(zhǔn)規(guī)范大多建立在同步協(xié)議之上,適用于較為簡單的非實(shí)時(shí)計(jì)算環(huán)境,難以滿足復(fù)雜、動(dòng)態(tài)的異步信息處理需求。本文提出了一種異步網(wǎng)絡(luò)處理服務(wù)實(shí)現(xiàn)方法,以網(wǎng)絡(luò)處理服務(wù)(Web processing service,WPS)和網(wǎng)絡(luò)通知服務(wù)(Web notification service,WNS)為核心,擴(kuò)展了標(biāo)準(zhǔn)的網(wǎng)絡(luò)處理服務(wù)請求,從而支持異步調(diào)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.
