Combined Block Adjustment of APR Data and Independent Photogrammetric Models*

Abstract

Based on the computer program PAT-M for block adjustment by independent models, an extended system is presented for the combined simultaneous block adjustment of photogrammetric models with APR and/or statoscope data, including photogrammetric height measurements of shorelines of lakes, if available. The system is intended for small- and medium-scale topographic mapping. Because of possible application to very large blocks, is is expected to be of great economic importance. The paper develops the basic mathematical formulas for the combined adjustment. In view of efficient and economic computation, some modifications are proposed, which the present programing of the system takes into account.
