The WCS Interface Standard ( http://www.opengeospatial.org/standards/wcs) specifies an application programming interface (API) for requesting coverage data, such as imagery, from one or more distributed sources.
The WCS 1.1 Transaction Extension defines how WCS clients can request that a WCS server import one or more new coverages into that server, update existing coverages, and/or delete existing coverages.
The WCPS Extension adds a raster expression language to WCS which allows analysis and processing of multi-dimensional grid coverage data over the World Wide Web. Resulting coverages can be transmitted directly or made available for download by URLs communicated to the client.
The Request for Comments (RFC) document can be downloaded from http://www.opengeospatial.org/standards/requests/49. Comments are due by July 30, 2008.
The OGC® is an international consortium of more than 365 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available geospatial standards. OpenGIS® 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.
