Simple Features SWG


Herring, John (Oracle USA)
Scarponcini, Paul (Bentley Systems, Inc.)

Group Description:


1.    ISO Simple Features

A Standard working group is being formed to work on the ISO version of the Simple Features specification. The intent is to create a fully harmonized standard so that the OGC and ISO standards and the SQL/MM Part 3 spatial versions are harmonized at the end of the work of the  SWG. A summary SWG description is given here and expanded below:

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.

USGS Interoperability Assessment

The rigorous testing of USGS web services performed in the Interoperability Assessment Project helped us identify and correct shortcomings of our implementation of OGC standards, and highlighted areas in which to improve the user experience with our web services.  As a result of the project, our users can include the improved USGS services more easily in their decisions making and operational activities.

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.

Data Quality DWG


Cunningham, Patrick (Blue Marble Geographics)
Beare, Matt (Beare, Matthew)
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.
