The xxx-DEM.tif output files seem to have units of meters asl (correct?), but what are the units and values of the xxx-COLOR.tif files? They have a broader range and start at 0.
Yes, the GeoTiff DEM is in meters ASL. There are no units for the COLOR.tif. It is a picture that shows the terrain shape with shading. There are no useful units in there.

Thanks for the quick reply. Still confused though, as the color scale on COLOR.tif definitely correlates with elevation, though I do see some shading in there too. (This was generated in 2018, if that makes any difference.)
There are 3 bands for 3 colors: Red, Green, and Blue. I could see how one color fading into another to form a gradient in colors might look like it tracks but it is not an elevation value.
I see, thanks. The color version looks to be much higher resolution than the DEM. Is the DEM smoothed?
