Block triangulation with aerial and space imagery using DTM as control information

For certain applications of photogrammetric point determination DTM data can be used as control information in the block adjustment. The results of a large practical project are reported, where DTM data are used in aerial trangulation for the subsequent production of orthophoto maps. Further simulations are described, which were carried out to study the use of DTM information in connection with digital three-line scanner imagery from space, based on the camera and flight paramters of the German MOMS-02/D2 project. -from Authors
