Besides the single transmission levels also the correla
tions between atmosphere, aircraft, imaging system and data
carriers diminish the quality of remote sensing data.
The most important sources of quality reserves are the
improvement of acquisition of orientation data, of naviga
tion and attitude stabilization of aircraft, dynamic or/and
electronic compensation of bluring and distortion influen
ce of angular (rotatory) movements, and the increase of
specific information content of remote sensing recordings
in connection with the correspondi ng image processing. For
it a concept for the introduction of a data preparation
system is presented which is orientated on practical use.
Further qualitative and economical effects
by the use of multi sensors in connection
concepts.

1. Problems of data acquisition from aircraft
The results found with new and improved imaging systems
laboratory and flight test conditions on the ground were
not obtained throughout in practical routine flights. It
was thus necessary to investigate the causes of negative
influences under practical conditions and to initiate
counteractions.
Investigations led to the result that an essential reason
is the interaction between the imaging system, its data
carrier, the aircraft, and the ambient atmosphere. The com
plexity of the overall process required largely interdisci
plinary cooperation.
