Set the lower bounds in the z-dimension for each location in the x and y dimensions from a raster.
A 2D or 3D MKDE object created with
A RasterLayer object representing the lower bounds of the space the animal may occupy in the z-dimension.
This function sets the lower bounds of the space the animal may occupy
in the z-dimension. For example, the
may represent a raster for elevation, depth of the sea floor, or other
An updated MKDE list object is returned.
