Improvement of the Automatic Moms02-p Dtm Reconstruction

Using high resolution optical satellite imagery for automatic DTM generation the validation of the digital terrain model becomes an issue. This problem is easily to overcome if a DTM already exists, as given in various European countries. For the validation of the MOMS02-P camera experiment the outcome of the data take M2P083C of March 14, 1997 is compared with the archived DTM of the Bavarian state survey department. The reconstructed MOMS-DTM has a size of 50kmx178km, within an estimated overall accuracy of about 11.6m. Investigations have shown, that this figure can be broken down taking into account various landscape types. This is necessary to come close to the expected height accuracy of the MOMS02-P experiment, what should be in the order of 6-7m.
