Web Map Service


The Web Map Service (WMS) allows software clients to reference map images over the Internet or a private intranet. The WMS implementation is based on the WMS 1.1.1 and 1.3.0 OGC specification. Using HTTP GET requests, the WMS provides georeferenced data to a client that displays this data as an image. Georeferenced data is information associated with maps that describe the real world extents of specific features and the projection upon which it is based.

The images can be provided as GIF, JPEG, PNG, and other image formats.

The Web Map Service is an OGC-compliant web service.
