GEOMETRICAL QUALITY OF LUNAR MAPPING BY PHOTO GRAMMETRIC METHODS
Abstract
At present, the preparation of lunar maps re quires the aid of photogrammetric methods. For such mapping as well as for all other kinds of mapping, it is most important to determine the geometrical quality to be expected in planimetry and elevation. Topographic mapping of the earth can be checked with ordinary geodetic methods, but for obvious reasons, the geometrical quality of lunar mapping can be checked in a similar manner only after man has landed on the moon. Therefore, the only possibility is to determine the basic accuracy of the photographic material and the operations to be used for the mapping and then apply the laws or error propagation. In this paper an attempt has been made to apply ordinary photogrammetric theory of errors and statistical methods for the determination of the final geometrical quality to be expected. Since no information is available concerning the accuracy of the image coordinates of the lunar photographs, the condition of the intersection of reconstructed rays has been used in a manner similar to that which has been successfully applied for the determination of the geometrical quality of ordinary aerial photogrammetry. The derived formula systems and the procedures used are of an approximate character but give information about the quality to be expected under different assumptions concerning the basic geometrical data.
