Notes:

1 Mixed terrain refers to a mixture of flat and moderately sloped terrain, with slopes up to +/- 35 degrees

2 TEC is the US Army Topographic Engineering Center - Ray Norvelle was report author.

A separate report on this data set was written by Carling and Davis, with similar results

3 INS is the Institute of Navigation at the University of Stuttgart, Germany - A. Kleusberg and H.G. Klaedtke were authors

4 NASA Stennis Space Center did the evaluation. Ground truth DEM supplied by USDA-ARS for the San Pedro Watershed Sub-Basin 11

5 Norvelles' report was very detailed and in it he noted a number of anomalies in certain situations (ravines, slopes, trees)
