Archeological Surveys

Bendix, with IAC assistance found that aerospace scanning techniques can uncover features of prehistoric ruins not visible in conventional aerial photographs. Chaco Canyon, a pre-Columbia Anasazi site in northeastern New Mexico, is a national monument that has been well explored on ground and by aerial photography. The National Park Service was interested in potential of multispectral scanning for producing evidence of prehistoric roads, field patterns, and dwelling areas not discernible in aerial photographs. Multispectral scanner produces image data in invisible as well as visible portions of spectrum. Data is converted to pictures which bring out features not visible to the naked eye or cameras.
