Automatic digital aerial triangulation is reviewed. It depends essentially on the automatic selection and transfer of tie points by digital image processing. The MATCH‐AT system is briefly sketched. Its basic design parameters are feature based matching, use of tie point clusters and integrated block adjustment. The system runs almost completely in batch mode, with as little interactive interference as possible. Some test results are discussed which confirm the general expectation that automatic digital aerial triangulation is faster, more precise and less costly than conventional aerial triangulation.
