Photogrammetric point determination and DEM generation using MOMS-2P/PRIRODA imagery

Abstract

This paper describes the process of photogrammetic point determination by bundle adjustment using three-line imagery collected by MOMS-2P, the German Modular Optoelectronic Multispectral Stereoscanner. Since May 1996 MOMS-2P is attached to the remote sensing module PRIRODA of the Russian space station MIR. For the photogrammetric evaluation 9 image scenes of orbit T083C were composed to an approximately 415 km long image strip covering parts of Southern Germany and Austria. For the German part control points provided by AMilGeo (Amt für Militärisches Geowesen) were used as ground control, with an accuracy of 1.5 m in X,Y and Z. According to experiences of earlier MOMS data evaluations the camera geometry is simultaneously estimated by self calibration methods. Using small subsets of 12, 7 and 4 control points empirical accuracies of approximately 8 m in planimetry and 10 m in height are achieved, verified by 141 independent check points. Finally a digital elevation model is produced for the entire area (about 50 km x 100 km), which is imaged by all three stereo channels.
