SAA Pilot

The Federal Aviation Administration (FAA) SAA Dissemination OGC Pilot demonstrated the feasibility of automating the dissemination and portrayal of Special Activity Airspace (SAA) information (including updates) to National Airspace System (NAS) stakeholders and other external users via OGC Web Services.

GeoSynchronization 1.0 SWG

GeoSynchronization Service
Agile spatial data infrastructures based on OGC standards allow content provider organizations to deploy increasingly efficient networks capable of responding to dynamic requirements for using geospatial or location referenced content. In this context, content provider organizations are being more and more called upon to deliver current, timely and verified data over the World Wide Web.

Emergency & Disaster Management DWG

The purpose of the EDM DWG is to promote and support the establishment of requirements and best practices for web service interfaces, models and schemas for enabling the discovery, access, sharing, analysis, visualization and processing of information to the forecasting, prevention, response to and recovery from emergency and disaster situations.

Simple Features SWG

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:


ISO 19125: Simple Features


Update the ISO 19125 (OGC) Simple Features standard to


The goal for the OGC GeoSPARQL standard is to support 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.

The preliminary work on a draft of the candidate standard has been completed. As soon as possible, the SWG hopes to approve a 30 day Request for Comment for the candidate standard to the OGC Technical Committee and to the public. The resulting comments will guide the GeoSPARQL SWG in the finalization of the implementation standrrd, hopefully to be ready for a final standardization vote by OGC before the end of 2011.

HDWG Surface Water IE

This interoperability experiment will advance the development of WaterML 2.0, test its use with various OGC service standards (SOS, WFS, WMS and CSW). It will also contribute to the development of a hydrology domain feature model and vocabularies, which are essential for interoperability in the hydrology domain.


1.    CF-NetCDF 1.0 Standards Working Group
NetCDF (network Common Data Form) is a data model for array-oriented scientific data, a freely distributed collection of access libraries implementing support for that data model, and a machine-independent format. Together, the interfaces, libraries, and format support the creation, access, and sharing of scientific data.
