To evaluate the adequacy of the Yuma Proving Ground as a test site representative of world desert conditions, the extent of occurrence of Yuma terrain types in the Northwest African NWA and other world desert areas must be determined. In order to make valid comparisons, a uniform system of describing, mapping, and comparing desert terrain must be employed. In this report both the Yuma and NWA deserts are mapped in terms of general or aggregate terrain, geometry, ground, and vegetation factors. General terrain factors include physiography, hypsometry, and landform surface conditions. Geometry and ground factors are characteristic plan-profile, occurrence of slopes greater than 50 percent, characteristic slope, characteristic relief, soil type, soil consistency, and type of surface rock. Terrainfactor data are synthesized to establish the degree of analogy of a particular NWA area with selected portions of the Yuma Proving Ground.
