This thesis traces the acquisition and potential applications of 35 mm aerial photography as a tool in helping to make decisions in the allocation of land to forest recreation. The advantages of the 35 mm aerial system, including its versatility, simplicity, applicability, and relatively low cost, were tested and applied to the field of forest and wildland recreation. Dealing first with the technology and equipment available, methods of acquiring the imagery were investigated, experimented with, and adopted. Then, working with the results of eleven hours of flying time, photogrammetric and photointerpretive techniques were applied to the reflected attributes of the physiographic, edaphic, hydrologic, and vegetative environments. In addition, the use of the system was investigated for recording recreational use on existing sites. The 35 mm aerial system can help identify those attributes of the land important to forest recreation. In addition it has benefit in the closely related fields of archaeology, protection, and wildlife and in evaluating hazard potential. Used in conjunction with either the small scale imagery soon becoming available through the Earth Resources Technology Satellite Program or existing air photos, the 35 mm system can accurately capture and monitor changes in the natural and artificial environments at a relatively low cost and assist the forest manager in decisions relating to the allocation of forest land to recreational use. / Forestry, Faculty of / Graduate
