A web service enables developers of Oracle Spatial GeoRaster applications to provide raster data and metadata to their application users over the web. GeoRaster supports Open Geospatial Consortium (OGC) web services, specifically, Web Coverage Services (WCS) and Web Map Services (WMS).

WCS offers multidimensional coverage data (imagery and gridded rasters) for access over the Internet. You can publish GeoRaster objects in the database and allow users to retrieve the raster data over the web, including subsetting, reprojection, and GeoTIFF format support. WCS is described in a chapter in the Oracle Spatial Developer's Guide.

MapViewer supports the rendering of data delivered using the OGC Web Map Service (WMS) protocol, specifically the WMS 1.1.1 and 1.3.0 implementation specifications. It supports any images and gridded rasters stored in GeoRaster. WMS is described in an appendix in the User’s Guide to Oracle MapViewer.
