Abstract

The Modular Optoelectronic Multispectral Scanner (MOMS-02) has been flown successfully on the German space shuttle mission D2 in April/May 1993. Its outstanding feature is along- track stereoscopic imaging. The imaging mode 3 of MOMS is combining the two off-nadir panchromatic channels with two nadir-looking color channels (red and near infrared). The ground pixel size is 13.5 X 13.5 m², and the base to height ratio is about 0.8. The paper reports on results of the photogrammetric evaluation of MOMS mode 3 data on Mexico (D2 orbit 82) and on Ethiopia (D2 orbit 61). The evaluation is subdivided into three major steps: (1) Automatic Imaging Matching to derive large numbers of conjugate points, performed with software which has been developed at DLR for the common Indian-German stereo scanner project MEOSS. The software has been successfully applied to MEOSS airborne imagery. (2) Combined Point Determination for the reconstruction of the exterior orientation and the calculation of the ground coordinates of a subset of conjugate points using the photogrammetric bundle adjustment software CLIC developed at Technical University Munich. For Ethiopia empirical accuracies of 23 m in X, 19 m in Y and 13 m in Z were obtained using 34 independent check points. Generation of a Digital Terrain Model from a dense network of conjugate points, which previously are transformed into object space by multiple forward intersection. For the Ethiopian example the conjugate point network was densified by additional image matching. The algorithm is based on the region growing approach, proposed by Otto and Chau. A report on the results achieved is given.
