This test map is based on data for the Grand Canyon. The map has two cells and six levels of detail for each cell. Here is a reduced version of the colormap
and normal map
The map does not have a water mask (I will add one, if I get the time).
The map is available here as a zip file [72,405,506 bytes]. This map will also be available on the CSIL Macs with the path /data/gcanyon.
