Finally, the outlook on sensor orientation has indicated 
that orientation data will be most essential for the geome- 
tric performance and hence for the photogrammetric appli- 
cation of scanners, linear array cameras and laser profilers. 
Airborne orientation data may promote a break through of 
such modern sensors sooner than anticipated. 
The conclusion must be that photogrammetry must prepare it- 
self for such developments and study the problems and the 
methods to be applied. There is no doubt that a major change 
in photogrammetric working methods is due, concerning the 
orientation of photographs and of other sensors. The develop- 
ment is of great importance as it will make photogrammetry 
more economic and more versatile than ever before.
