Layer group

A layer group, as its name suggests, is a collection of layers. A layer group makes it possible to request multiple layers with a single WMS request. A layer group contains information about the layers that comprise the layer group, the order in which they are rendered, the projection, associated styles, and more. This information can be different from the defaults for each individual layer.

Layer groups do not respect the concept of workspace, and are relevant only to WMS requests.
