Experimentation in overhead photography aimed at eliminating errors in measurement by conventional mapping techniques has resulted in the development of instruments having from one to several applications in intra-site mapping. A useful by-product of this research has been the achievement of superior panoramic views. Since altitude is a critical factor in achieving either of these objectives, this paper distinguishes the results to be gained by use of low, medium, and high altitude instruments. The paper concludes with some overall field considerations along with photo-laboratory suggestions especially directed toward producing a photographic montage of the site as a whole.
