Abstract
In connection with the precision of photogrammetric measurements, there has been a great deal of experimentation, theoretical and practical, in Japan and elsewhere. Moreover, recent mechanical and technological progress has brought about a notable enhancement of precision. For instance, when pictures taken with the wartime Metrogon lens are compared with those obtained with the Aviogon or Pleogon lens, a general evaluation of the performance, as regards precision, resolving power, etc., would be "about a four-fold improvement". Indeed these Aviogon and Pleogon lenses are continually being improved for color use, infrared use and reseau camera use, and their level of performance is rising; in precision plotters too, with mechanical improvements, introduction of analytical methods and so forth, the accuracy is becoming very good and the method is finding application in operations demanding high accuracy: in earth volume calculations, highway planning, numerical cadastral work, and so
