ABSTRACT 
A novel photogrammetric mensuration procedure is 
described, which does not need the assumption of 
metrically correct photographs, or the assumption of 
additional parameters to compensate for deformations. The 
approach is based on measuring and processing appropriate 
differences of the image coordinate. The approach is 
superior to conventional photogrammetric methods and is 
essential for good results in satellite photogrammetry, 
and when using non-metric cameras.
