WCS 1.1.2 Processing extension Request for Comment
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.
