The choice of quasi-observations at x, intervalls essentially makes the process a mixture between a
deterministic and a stochastic approach.
The adjustment proceeds as usual with the following steps:
1. determination of approximations for the exposure stations and of unknown points from a map,
assuming the approximations for the rotations to be zero;
2. calculation of computed image coordnates for all control (and ground) points using approxima-
3. formation of the error equations: for all image points
for all constraints
