adapted to exposures that are not normal. In the same way, the
convergent networks possess a high degree of redundancy that
must be used to generate a robust DSM.
Finally, it must be noted that DSM are not authentic three-
dimensional models since the hidden areas (folds) may not be
modelled. This is not excessively important for the construction
of orthoimages but renders the construction of true 3D models
impossible. The path towards this objective demands a deep
revision of the algorithmic basis implemented in current
photogrammetric applications.
