 <p>A Web Coverage Service (WCS) loads raster data in a similar way as Web Feature Services (WFS) load vector data. <a href="https://www.opengeospatial.org/standards/wcs">Web Coverage Services</a> are a standard by the Open Geospatial Consortium and allow the downloading of geospatial raster data with multiple types of format encoding: GeoTIFF, netCDF, JPEG2000 etc. A <a href="https://www.opengeospatial.org/standards/wms">Web Map Service</a> [WMS] also exists for rasters; it allows downloading of images but without the data values.</p>
