Layer Properties

WMS layer represents a basic unit of geographic information that may be requested as a map from a server. The layer element can enclose child elements providing metadata about the layer. The meanings of those metadata elements are described in the table below:

Property	Description
Abstract	Represents a narrative description of the map layer.
Name	Name of the map layer.
Title	Human-readable name of the map layer. It also appears in the layers tree picker on the right side of the wizard page.
Opaque	If true, indicates that the layer represents an area-filling coverage. For example, a map that represents topography and bathymetry as regions of differing colors will have no transparent areas. The opaque declaration should be taken as a hint to place such a layer at the bottom of a stack of layers.
Queryable	If true, indicates that WMS server supports GetFeatureInfo operation on that layer.
Cascaded	If true, indicates that the layer was obtained from an originating server and then included in the service metadata of a different server.
Subsets	If true, indicates that the server is able to make a map of a geographic area other than the layer's bounding box.
Legend	Represents a graphical legend of the layer contents.
