29 May 2014 - The Open Geospatial Consortium (OGC®) Membership
has approved six OGC Web Coverage Service (WCS) Interface Standard extensions
as official OGC standards. These WCS extensions significantly expand the
ability of researchers, environmental managers, disaster managers, policy advisers
and others to access the world's network-distributed Earth imaging data resources.
The OGC Web Coverage Service (WCS) Interface Standard defines
an interface for requesting coverage data, such as sensor data, satellite
imagery, image time series, point clouds, and TINs (triangulated irregular
networks). The six new WCS Extensions specify standard mechanisms for providing
additional control over the processing of a coverage during its server-side
• GML Application
Schema - Coverages - GeoTIFF Coverage Encoding Profile: Returns a coverage in GeoTIFF encoding, in addition to formats like the OGC Geography
Markup Language (GML) Encoding Standard.
• WCS Range
Subsetting Extension: Specifies a
standard way to extract specific fields from the range set of a coverage as
part of the data request. For example, in remote sensing this is known as
“band” or “channel” subsetting and in climate modeling it is called “variable
• WCS Scaling Extension: Specifies parameters to a request to provide control
over scaling of a coverage during its server-side processing.
• WCS Interpolation
Extension: Enables clients to specify the interpolation method that the server
shall apply to a coverage.
• WCS Processing
the standard service interface to the Web Coverage Processing Service (WCPS) query
language. WCPS extends WCS functionality with a high-level query language for
server-side filtering and processing of multi-dimensional Big Data.
• WCS Earth
Observation Profile: Defines a profile of WCS 2.0 for use on Earth Observation
All OGC standards are free and publicly available at http://www.opengeospatial.org/standards. An
overview and downloads of the complete WCS suite are available at http://www.opengeospatial.org/standards/wcs.
The OGC is an international consortium of more than 475
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 http://www.opengeospatial.org/contact.
