Not only the geometric conditions are important. For mapping the object identification 
is also important. The visibility of objects is depending upon the radiometric and the 
spectral resolution.

4. Geometric conditions 
The mentioned space images have been used for mapping by the University of 
Hannover. The data aquisition was based on analytical plotters because of the 
special geometry of the images and the special situation of small scale photographs. 
Only the MC, the center part of the LFC and the KATE 200 can be handled in 
analog plotters. In addition the earth curvature cannot be neglected and also the 
influence of the map projection is exceeding the mapping tolerance (Jacobsen 1986). 
The traditional photo orientation with relative and absolute orientation is causing 
problems in the case of very small angle photographs and in addition it will not lead 
to the optimal results. By this reason, the most rigorous solution by bundle 
adjustment has been used. This enables also the determination and respection of 
systematic image errors. The photo orientations determined by bundle adjustment 
with program BLUH have been used directly for the orientation of the analytical 
plotters.
