The Department of Defense (DoD) operates a network of test and evaluation centers located in variety of natural environments and extreme climatic conditions for the purposes of developmental and operational testing of equipment, training and doctrine support, and surveillance and security operations. To effectively accomplish these objectives, the physical and environmental geography, as well as cultural resources, of these sites must be understood, managed, and in some cases protected. This dissertation initially focused on the use of remote sensing technologies for installation environmental impact management and cultural resource evaluation. Successful application of aerial photograph and multispectral satellite imagery interpretation, integrated with a Geographic Information System (GIS), provided considerable improvements in survey archeology for a portion of the U.S. Army Yuma Proving Ground (YPG) in Arizona. This initial success provided a vision of quantitative analysis of hyperspectral data having potential for improved desert characterization.
