Web Map Service
The OpenGIS® Web Map Service Interface Standard (WMS) provides a simple HTTP interface for requesting geo-registered map images from one or more distributed geospatial databases. A WMS request defines the geographic layer(s) and area of interest to be processed. The response to the request is one or more geo-registered map images (returned as JPEG, PNG, etc) that can be displayed in a browser application. The interface also supports the ability to specify whether the returned images should be transparent so that layers from multiple servers can be combined or not.
NOTE: WMS 1.3 and ISO 19128 are the same documents.
Note: You may also download All Official OGC Schemas in a single zip file.
This specification is currently stable, however, Working Groups are put in place to actively address future changes.
