Adjustment of a photogrammetric block located in the city of Sudbury, Ontario, demonstrates that an accuracy of 2 cm in planimetric coordinates can be achieved using a minimum number of control points if additional constraints in the form of observed spatial distances are combined with the photogrammetric mathematical model to reduce the control point requirement. This accuracy has been estimated by error ellipsoids of the adjusted ground coordinates, and by independent field checking. The data have also been used to compare different mathematical functions for the compensation of systematic errors in the method of bundle adjustment with self-calibration.
