Computer supported geological photo-interpretation

Abstract

The research project supported by the Danish Natural and Technical Science Research Councils (SNF & STF) and GGU aiming at evaluating the use of advanced photogrammetrical techniques in geological photo-interpretation (Dawes, 1977) has continued during the past year. Methods which combine geological photo-interpretation with photogrammetrical techniques have been described by Dueholm (1976) and Dueholm et al. (1977). This report describes a procedure and an instrumentation which makes it possibIe to combine precise drawing of geological boundaries with computer supported interpretation. 300 km2 of south-eastern Washington Land, western North Greenland was selected as a test area. 10 vertical aerial photographs at a scale of about 1:50000 cover the area.
