GeoSPARQL - A Geographic Query Language for RDF Data

The OGC GeoSPARQL standard supports representing and querying geospatial data on the Semantic Web. GeoSPARQL defines a vocabulary for representing geospatial data in RDF, and it defines an extension to the SPARQL query language for processing geospatial data. In addition, GeoSPARQL is designed to accommodate systems based on qualitative spatial reasoning and systems based on quantitative spatial computations.

Geospatial Semantic Web Interoperability Experiment

Initial Plan

This Interoperability Experiment (IE) will address several important steps towards the development of a Geospatial Semantic Web (GSW), where discovery, query, and consumption of geospatial content are based on formal semantic specification. Many pieces of the GSW puzzle have been worked extensively in the last several years; this experiment aims to augment WFS/FE with a semantic query capability, through the definition of an ontology for the geospatial intelligence community.

Guthrie, Christian (US National Geospatial-Intelligence Agency (NGA))

Group Description:

The mission of the DQ DWG to establish a forum for describing an interoperable framework or model for OGC Quality Assurance measures and Web Services to enable access and sharing of high quality geospatial information, improve data analysis and ultimately influence policy decisions.
