1. Web Coverage Service (WCS) SWG
The WCS.SWG is a standing WG working on the Web Coverage Service (WCS) suite of standards. A coverage is defined as a "space-time varying phenomenon", such as 1D sensor time series, 2D remote sensing imagery, 3D x/y/t satellite image time series and x/y/z geophysical data, as well as 4D x/y/z/t atmospheric and ocean data. A normative abstract definition of coverages is given in OGC Abstract Topic 6 (which is identical to ISO 19123), a concrete definition is provided with the OGC GML Application Schema for Coverages.
