- 4 - The following report on "Photogrammetric Distortion" by Dr. Scholer defined the term "distortion" as a symmetric rotation of the image point between the mathematic model of the perspective projection and the point physical image. The sum of an unavoidable tolerance in the construction of the optical system overlaps said physical distortion, wherefrom the term "deformation" has been derived. Some further discussions led to the conclusion that at the present knowledge level other factors may occur in the model production which cannot yet be entirely defined. However, assuming that model deformations may be originated by a faulty geometry of the photogram, it could be advantageous to compensate them by means of correcting surfaces analytically established. Further critical comments were then made on the conventional and classic solutions generally adopted. Dr. Schwebl reported about the importance of the digital technology for the photogrammetric field, specifically for the out-of-line processing, such as the block triangulation. Photogrammetric technique with out-of-line calculation has achieved such a level at present that it is now possible, for the first time, to fully use the accuracies that can be obtained by photogrammetric devices. An essential question for the future in respect to manufacture of photogrammetric devices is to what extent said digital technology can be used to increase efficiency of devices, i.e.
