In this Issue: "Seeing" the Big Picture /2 (The impact of large-scale construction projects on the environment is great. Frequently, the physical consequences of these projects are of greater concern to engineers than the actual problems of design and construction. Professor Donald J. Belcher, director of the Center for Aerial Photographic Studies, examines the engineer's need to predict and control complex factors in the environment and his resultant reliance on gaining a larger perspective than that obtainable from the ground. Aerial photography provides such a perspective and allows for optimum design at the maximum savings in cost.) ... The Use of Airphotos in Tropical Development /12 (Professor Ta Liang of the Department of Geotechnical Engineering offers his special insight into the unique ground conditions and problems associated with the tropics and their development. He draws from his extensive experience with aerial photography in central Africa, South America, and western Australia to illustrate the kinds of development projects that are heavily dependent on airphoto interpretation for their success.) ... Photogrammetry: Recent Developments and Applications /18 (Photogrammetry and satellites; . . . and mapping; . . . and calibration; . . . and sculpture; . . . and architecture; . . . and medicine. The list of fields with which photogrammetry can be teamed to provide more efficiently and accurately the data needed by modern engineers is seemingly endless. Professor Arthur J. McNair of the Department of Geotechnical Engineering, discusses in detail some of these applications of photogrammetric methods.) ...
