. MAP MAKING IS . BEING ALTERED Amtmn Adds to Skill in Picturing Areas Dayton. O., Aug. 21 (F—New de- velopuients in aerial photography, achieved in the experimental labor- atories of the United States army air corps at Wright field, are expected to revolutionize the science of map making. For centuries men have carried on the weary task of accurately map- ping the world. United States en- Eineers alone have been more than a century {n attempting to complete detailed maps of the United States and the task is still far from com- Bpletion. They also face the problem 9t correcting their studies as topo- graphical features change from year to year. The mapping of a single square mile under present methods requires weeks of work. Now the actual photographing of & state as large as Ohio, says T. C. McMahon, chief of the technical data section at Wright field, can be accomplished with airplanes and the latest camera equipment in little more than a month, "Additional weeks, of course,” he continued, “‘would be necessary to correct errors and to complete the finished maps in the photographic laboratory. But that, at least, gives some idea of the time saving ele- ment involved in aerial map pho- tography over the old methods.” Capt. Albert W. Stevens, chief of the experimental photographic sec- tion at Wright field, and Lieu.t John A. MacReady, former altitude record holder, demorstrated the pos- sibility of mapping an entire city of 19 square nules with a single shot of the cemera. They made a map photograph of the city of Dayton from an altitude of more than six miles. Maupping large areas with a single {lens camera from such a high alti- tude would not be practical in the systematic mapping of a state or nation. but shows the possibilities of developing accurate maps from aerial photographs taken in a frac- tion of the time ordinarily required for engineers to map the same sec- tion. Multiple lens cameras, perfected in the Wright field laboratories, are Lelieved to hold the solution te map- ping large areas at one snap of the shutter. planes flying several thousand feet above the ground, can cover more than 10 Omiles of territory an hour, preserving a record of the ground beneath as they go. The detailed maps then are cor- rected and pieced together in a great mosaic, completed in the lab- oratory. New photographs are taken of the map mosiacs to produce the finished map, which is far more ac- curate and detailed than those ob- tained by engineers working in the field. The United States air corps has completed a map of the District of Columbia through the mosaic meth- od and it has been declared by ex- perts the most perfect, clean cut piece of work produced.
