Application	ISO 19128 describes the interface for a Web Map Server (WMS). WMS allows a client to request a map image, for example, a JPEG file, from a web service. OpenGIS Web Map Tile Service Implementation Specification is a similar standard.
Conformance classes	Basic WMS Queryable WMS
Implementation benefits	Through implementing a WMS interface, data can be exposed in a standardized way so that any client familiar with the WMS interface can request a map image of available data. The client specifies parameters, such as the data source, bounding box, and symbology, for the map, through the interface. WMS does not generate map elements, such as a legend. The service can be reused by different clients and is more cost effective than developing a custom service.
Products	deegree 3.3 is an example of an OGC compliant open source implementation of the WMS interface. GeoServer 2.5.2 is an example of an open source implementation of the WMS interface. These implementations are generally easy to use, and libraries, such as OpenLayers, have integrated support for WMS calls.
