Standard supports electronic retrieval of geospatial data like satellite imagery or digital elevation models as ‘coverages’
The Open Geospatial Consortium, Inc. (OGC®) seeks public comment on the draft OGC Web Coverage Services (WCS) Interface Standard Version 2.0. The OGC WCS standard supports electronic retrieval of geospatial data as ‘coverages’ – that is, digital geospatial information representing space/time-varying phenomena such as satellite imagery or digital elevation models. The WCS 2.0 draft has several significant enhancements over previous versions. WCS 2.0 is harmonized with the Geography Markup Language coverage model, leading to increased interoperability across OGC standards. Further, WCS 2.0 is highly modular and follows the core/extension design pattern, which allows for standard that is easier to understand and implement.
The WCS standard defines a standard interface and operations that enable interoperable access to single or multi-dimensional geospatial
coverages. Services implementing this standard provide an interface with a standard set of operations for accessing original or derived sets of geospatial coverage information. An important aspect of the WCS standard is that it allows access and retrieval of raw, unprocessed imagery, which is often required by rendering and processing services. Further information about WCS can be found at the WCS Service page ( http://www.ogcnetwork.net/wcs ) of the OGC Network.
