Web Map Services

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 (open geospatial consortium).
