PHOTOGRAMMETRIC ENGINEERING Thus, enthusiastic and unlimited production of air photo interpretation keys for existing world coverage is a nearly endless task, if not one of question able value. It is likely to be more efficient to postpone making new keys until the need for specific ones is demonstrated for specific projects. Air photo interpretation is a technique belonging to all fields of study. The procedures are similar to those of map interpretation, language translation, statistical manipulation, and field observation. Also, successful air photo inter pretation is based upon the use of all available source materials, photographic and non-photographic. Therefore, the value of the technique may be overem phasized thereby doing it an injustice, in our enthusiasm to classify researchers as “photo—ists(ers)”; such analysts use other techniques and source materials and the term is the equivalent of calling a person a “hammer-carpenter.” Too, there is hardly any such person as an “air photo interpreter,” unless temporarily for educational or administrative purposes, because no one proposes to use just air photos, nor do many people suggest by such a title that they can identify everything seen on any coverage of the world. It follows that the way to interpret air photos is simple in general terms. Work is carried on methodically from the general to the specific items, and from the known to the unknown features, in view of the photographic qualities available. Then we analyze topically. Thus, the more specific procedures are likely to come in the future from topical specialists (such as, geographers, city planners, geologists, foresters) who interpret air photos with breadth and depth of topical content, as well as other source materials and techniques. Problems in Comparing Photo Interpretation Research Results from Different Studies* earl j. ROGERS, 2333 Holmes Run Dr., Falls Church, Va., Forester, U. S. Forest Service Abstract: Quantitative data are increasingly becoming available in photo interpretation research. The task of evaluating these data for a particular study in view of other similar studies and the making of a comparative evaluation of the results, runs into problems. The author presents an example and offers suggestions to research workers in the field of photo interpretation so that research results can be compared with other similar studies. The Problem TN the past twenty years great progress has been made in all fields of photo ^ interpretation. During this period investigators have collected data to study * A contribution of Commission VII, Photographic Interpretation, International Society of Photogrammetry.
