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:
http://map.ngdc.noaa.gov/wmsconnector/com.esri.wms.Esrimap?BBOX=-180,-90,180,90
&WIDTH=1024&HEIGHT=512&SRS=EPSG:4326&Layers=Shaded%20Relief,DMSP%20Satellite
&version=1.1.1&service=WMS&FORMAT=PNG&TRANSPARENT=TRUE&request=getmap&ServiceName=nosa
These include several elements that users can customize to change the
maps:
