FICTITIOUS DATA GENERATOR FOR ANALYTICAL AEROTRIANGULATION.

Abstract

The report describes the development of a computer program designed to produce fictitious data for the testing of extensive programs of analytical aerotriangulation. The program generates the positions of ground points and exposure stations and the angular orientation elements for the photographs. From these, the theoretically correct image coordinates are computed. The correct image coordinates can be perturbed to simulate the effects of lens distortion, atmospheric refraction, film shrinkage, and normally distributed measuring errors. The number of photographs per flight, the number of parallel flights, and the number of image points per photograph can be selected by the operator. The area to be photographed can be located anywhere on the earth's surface, and the flight lines can be at any azimuth. Any geodetic figure can be adopted. The program has been used to generate several large blocks of data for testing other routines. (Author)
