An international consortium developing open standards for geospatial content, location services, and spatial data interoperability.

The Open Geospatial Consortium (OGC) is an international voluntary consensus standards organization that develops and maintains open standards for geospatial content and location-based services. OGC standards such as WMS, WFS, GML, and CSW enable interoperable sharing of geographic information across governments, industry, and research. OGC also collaborates with ISO Technical Committee 211 on the ISO 19100 series of geographic information standards, which includes the widely used ISO 19115 metadata standard for geospatial data.
