This example adds terrain, a national park service map, its alpha channel and a base map of aerial tiles to demonstrate the draping of a NPS map over terrain. A timer loop varies the alpha channel over time so that the aerial tiles and the NPS are both periodically visible.
Use normal panning and zooming, along with shift-pan and crtl-pan, to view the terrain from different angles.
See example #34 for details on downloading and converting NPS maps.
