Despite the, on first sight, promising results of the aerial
triangulations all test data sets showed an erroneous “Dome” in
the Digital Surface Model generation in the centre of the block.
The effect counted up to 10 meters in height as shown for
BezF1 and BezF6 (Figure 5). Even with the introduction of the
GPS flight recordings into the AT the lack of GCPs in the block
could not be compensated. It is more than obvious, that this
effect cannot be neglected for almost all possible applications.
