WebThis paper demonstrates how the area-based Multi-Photo Geometrical Constrained (MPGC) matching algorithm can be modified for the highly accurate measurement of object edges. It can be expected that this algorithm allows the measurement of non-targeted, but well-defined object features with a relative accuracy of 1:25000. Webes between the images. The proposed algorithm is based on a modiﬁed version of the Multiphoto Geometrically Constrained Matching (MPGC). It is the ﬁrst algorithm that explicitly uses the SPOT geometry in matching, re-stricting thus the search space in one dimension, and simultaneously providing pixel and object coordinates. This
