Experimental Raster GIS Options

These options require a reference DEM, ALOS, and COP DEMs.  They should all have the same spacing and pixel representation; if they do not, the results may or may not be valid. The results will a grid with integer codes and a VAT.  A good display for these is Variable opaque merge (two maps) with the grayscale Reflectance/Hillshade map of the reference DEM as the base layer.

• COP ALOS best locations; pick a tolerance, and the map will show which DEM is better at every pixel.
• COP ALOS categories:; pick a tolerance, and the map will show 4 or 9 categories at every pixel.
