What is WMS?
The Web Map Service (WMS) implementation specification is a standard that describes how mapped information should be communicated on the internet.  The Open Geospatial Consortium has come up with a number of versions of the WMS standard.  Currently, this site works with WMS versions 1.0.0, 1.1.0, and 1.1.1.
