OGC Web Map Services (WMS) available

The Open Geospatial Consortium provides a specification for serving geographic information through the web as georeferenced images; this is called the Web Map Service specification. In addition to providing a visible representation of selected geospatial data, it allows the scientific attributes of the data to be queried geographically. The services listed below conform to the WMS specification version 1.3.0 and earlier.
