The OGC provide a [detailed overview](http://www.opengeospatial.org/standards/wms) of the WMS standard.\n", "\n", "A WMS request to a WMS server contains layer (a map layer containing a given geographic phenomenon) and area of interest information. The information in the request defines the response from the WMS server to which the request was made. The response is composed of geo-located map images that can be displayed by the application making the request.\n", "\n", "The map images in a WMS response are raster images, typically provided in `PNG` or `JPEG` format.\n", "\n", "An important part of OGC standards services is the `get capabilities` request.
