3.2 Separability of gross errors and systematic image errors
in bundle block adjustments
By using the separability theory above an investigation about
the separability of gross errors and systematic image errors
has been done for the bundle block adjustment with different
geometry. The synthetic data of photogrammetric blocks are
used and the parameters are;
--- photo scale 1:10,000,
--- photo base bs 100mm ,
=== picture format 23cmx23cm,
--- camera constant c = 150mm,
--- tie points 3 x 3 in each photo,
The cont?ol point distributions and flight arrangements are
showed in Fig. 6 and Tab,3 respectively. The used additional
parameters are chosen from parameter set of Ebner(1976).

The separability of gross errors in control points and syste-
matic image errors has been estimated from 1 x 1 dimension to
9 x 12 dimensions ( Li, 1985 ). Here we only give some results
in order to indicate how dependent on the geometry the separa-
bility is. Fig.7 and Fig.8 describe the dependence of maximum
