5 April 2013 - The Open Geospatial Consortium (OGC®) announced a call for public comment on the OGC Web Coverage Service (WCS) Coordinate Reference System (CRS) Extension Standard. 

WCS defines an open standard interface to easily access multi-dimensional, spatio-temporal coverages, such as sensor data, satellite imagery, image time series, simulation data, point clouds, and meshes.

The OGC WCS CRS Extension defines an extension to the WCS Core that enables requests to specify that coverages be returned in one of a number of different Coordinate Reference Systems. While the WCS Core defines access only in the coverage’s Native CRS (i.e., the one in which the coverage is stored on the server), the WCS CRS Extension defines how to request and obtain a coverage in a CRS different from the Native CRS. This flexibility is important, for example, in exchanging data between different environments.

The OGC WCS CRS Extension is free and can be downloaded from the OGC Request for Comment page at

The OGC WCS Standards Working Group will consider all comments when preparing a final draft of the candidate standard. The comment period ends 5 May 2013.

The OGC is an international consortium of more than 480 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available geospatial standards. OGC Standards support interoperable solutions that "geo-enable" the Web, wireless and location-based services, and mainstream IT. OGC Standards empower technology developers to make geospatial information and services accessible and useful with any application that needs to be geospatially enabled. Visit the OGC website at
