Web Map Service

Web Map Service (WMS) defines a standardised way to use maps and other geo-referenced data from different services on the Internet, in order to create composite maps. A typical use will be to request a background map and one or more partly transparent maps, covering the same geographical area, from selected servers complying with the WMS standard. Each of these maps will be an image that constitutes a layer in the composed map. With such a standard protocol it is possible to compose any kind of maps, and the users of such systems are independent of the different map system vendors.

WMS is a standard defined by the Open Geospatial Consortium, Inc. (OGC). The AIS Server follows the WMS version 1.1.1 standard.

The figure below illustrates how the WMS standard can be applied by a client that sends map requests to selected map servers, and uses the resulting map layers to compose the final map.
