getExtent

public Extent getExtent()

Gets the bounding box in world coordinates. If the layer has defined the BoundingBox tag, we will take this bounding box as entire extension of this layer, else we'll see if the tag WGS84BoundingBox is defined (it can be approximated). In this case we'll take WGS84BoundingBox as entire extension.

Note:

If the layer has grid subsets (TileMatrixLimits) then this will have a only extent but if the layer doesn't have grid subsets then this will have a different extent in each level resolution. In this case we need to know the extent for each level.
