GeoServer serves data using standard protocols established by the Open Geospatial Consortium:
- The Web Map Service (WMS) supports requests for map images (and other formats) generated from geographical data.
- The Web Feature Service (WFS) supports requests for geographical feature data (with vector geometry and attributes).
- The Web Coverage Service (WCS) supports requests for coverage data (rasters).
These services are the primary way that GeoServer supplies geospatial information.
