OGC Seeks Public Comment on MetOcean profile and extensions to WCS 2.1

Extension to and Profile for WCS 2.1 will enable MetOcean community to
efficiently query and access required data contained in datacubes.

21 August 2018: The Open Geospatial Consortium (OGC) seeks public comment
on the MetOcean profile and extensions to WCS 2.1.
The Meteorological and Oceanography (MetOcean) community works with massive
datacubes
<http://mail.opengeospatial.org/lists/lt.php?tid=+UhIPjl3c4yiFeaE0NYhMRrX50xCkVU0iy8pI0CiXT7+IsiO79j38Zl/mflUmD9v>
of content organized in 4-dimensional space and time. Extracting valuable
information from these datasets requires efficient query and delivery of
the content perfectly suited to the user's needs.

The MetOcean community relies upon the OGC Web Coverage Service
<http://mail.opengeospatial.org/lists/lt.php?tid=GP0VvvoG5Ki1Sb6kbZpYTxrX50xCkVU0iy8pI0CiXT7+IsiO79j38Zl/mflUmD9v>
(WCS) to search and deliver such content. The community has developed a new
profile and two new extensions to WCS 2.1 to address MetOcean requirements.
The MetOcean Profile fully exploits the multi-dimensional nature of WCS2.1,
which is built on the new OGC Coverage Implementation Schema
<http://mail.opengeospatial.org/lists/lt.php?tid=vFbCHuWjXquf4pD9sFBibxrX50xCkRU0iy8pI0CiXT7+IsiO79g38Zl/mflUmD9v>
(CIS) 1.1. The GetCapabilities file size is reduced by almost 2 orders of
magnitude, making discovery much easier.

As the WCS2.1 core provides only general metadata, the MetOcean Profile
adds community-specific metadata to this core.
Additionally, the MetOcean Profile introduces the terms “Groups” and
“CoverageCollections” as a way to both efficiently access the data, and
structure the return of data. The main benefit of Groups is in creating a
structure that reflects the organization of the intended use of data,
rather than its underlying structure. This provides a hierarchical way of
nesting services. The main benefit of CoverageCollections allows for the
identification of collections of data for easier access to the data.
Two extensions have also been developed to facilitate retrieval of coverage
data according to the operational requirements of those using MetOcean
data. One extension specifies how to extract a corridor based on a
trajectory from a multidimensional coverage. The other extension defines
how to extract data contained within a polygon defined either by a set of
points or the radius and position of a circle point.
Through the addition of community-based metadata, Groups &
CoverageCollections, and the two new operations, the efficiency of both
MetOcean data access and retrieval has been increased substantially.

The candidate MetOcean profile and extensions to WCS 2.1 is available for
review and comment on the OGC Portal

About OGC

The Open Geospatial Consortium (OGC) is an international consortium of more
than 525 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 within any
application that needs to be geospatially enabled. Visit the OGC website at
