互操作性是在Web上高效查找和访问空间数据的主要挑战。开放地理空间联盟在互操作性方面作出了重大贡献，该联盟建立了发布和下载空间数据的网络服务标准。OGC GeoSPARQL规范通过为注释和查询提供全面的词汇表，将Web上的空间数据定位为链接开放数据（LOD）。虽然OGC Web服务标准在地理信息系统（GIS）中得到了广泛的应用，并提供了一个无缝的服务基础设施，LOD方法提供了结构化的技术来互连和语义描述空间信息。目前还不能使用LOD作为OGC Web服务的数据源。在本章中，我们提出了一个建议，在技术上连接OGC Web服务和LOD作为一个数据源，我们探索和讨论它的好处。我们描述和测试的适配器，使访问地理LOD数据集从OGC Web要素服务（WFS），使最新的GIS访问Web的数据。我们讨论的性能测试比较建议的适配器的参考WFS实现。
Interoperability is the main challenge on the way to efficiently find and access spatial data on the web. Significant contributions regarding interoperability have been made by the Open Geospatial Consortium (OGC), where web service standards to publish and download spatial data have been established. The OGCs GeoSPARQL specification targets spatial data on the Web as Linked Open Data (LOD) by providing a comprehensive vocabulary for annotation and querying. While OGC web service standards are widely implemented in Geographic Information Systems (GIS) and offer a seamless service infrastructure, the LOD approach offers structured techniques to interlink and semantically describe spatial information. It is currently not possible to use LOD as a data source for OGC web services. In this chapter we make a suggestion for technically linking OGC web services and LOD as a data source, and we explore and discuss its benefits. We describe and test an adapter that enables access to geographic LOD datasets from within OGC Web Feature Service (WFS), enabling most current GIS to access the Web of Data. We discuss performance tests by comparing the proposed adapter to a reference WFS implementation.
