Web Map Service (WMS)

The Open Geospatial Consortium Web Map Server (WMS) protocol defines a simple interface for web based mapping applications. The WMS protocol is based on a simple query syntax for posting a request for the desired layers and region to the server, which returns a map as a standard image (GIF, PNG or other format). The list below gives example WMS URL's for the NOAA Observing Systems. These URL's look like:


These include several elements that users can customize to change the maps:
