Capabilities<br />

This section names the actual operations that are supported by the service, the output formats offered<br />

by these operations, and the URL prefix for each operation. For most WMS services this section has<br />

three parts, one for GetCapabilities, one for Get<strong>Map</strong>, and one for GetFeatureInfo. The following example<br />

illustrates the Get<strong>Map</strong> section:<br />

Layers<br />

Within the Capabilities is a Layer element for each map that can be provided by the service. WMS also<br />

allows layers to be made up of layers so some nesting of layers can also be seen in these elements.<br />

Each Layer element includes the following:<br />

• Title – a name of the layer that is readable by the user.<br />

• Name – a name of the layer that is used to reference the layer in requests.<br />

• Style – a predefined style that can be used with this particular layer.<br />

• SRS – the spatial reference system(s) that applies to this layer. If more than one SRS can be used<br />

on the layer, each one can be listed.<br />

• LatLonBoundingBox – a set of attributes that state the minimum bounding rectangle of the map data<br />

in the default coordinate system (EPSG:4326). These numbers are expressed in decimal degrees<br />

These values are important when making a Get<strong>Map</strong> request, as that request requires the correct values<br />

that are specific to each individual <strong>Web</strong> <strong>Map</strong> service.<br />
