OGC seeks public comment on Web Coverage Service (WCS)

The Open Geospatial Consortium (OGC) seeks public comment on the Web Coverage Service (WCS) 2.1 candidate standard. The OGC WCS standards suite defines methodology to access coverages (regular and irregular grids, including spatio-temporal datacubes, point clouds, and general meshes) from the Web. OGC has offered WCS standards since 2005, reflecting the importance and maturity of providing such data to Web clients. The definition of a coverage is given by the OGC Coverage Implementation Schema (CIS). In 2017, CIS 1.1 was released as a backwards-compatible extension of coverages to CIS 1.0, with a unified grid model supporting any kind of spatio-temporal sensor, image (timeseries), simulation, and/or statistics data. By supporting the more general datacube model of CIS 1.1, the WCS 2.1 standard will simplify access to spatio-temporal ‘big datacubes’, with an operation spectrum ranging from simple subsetting in space and time up to complex spatio-temporal analytics through Web Coverage Processing Services (WCPS). www.opengeospatial.org
