WCS
The Open Geospatial Consortium (OGC) Web Coverage Service Interface Standard (WCS) defines Web-based retrieval of coverages, that is, digital geospatial information representing space/time-varying phenomena.
The OGC Web Coverage Service (WCS) supports electronic retrieval of geospatial data as "coverages". Coverages are digital geospatial information representing space/time-varying phenomena, specifically spatio-temporal regular and irregular grids, point clouds, and general meshes. WCS offer the means to retrieve or query geographic coverages in a manner independent of the format in which the data is stored.
