However, there are some restrictions which have to be taken into account. • • Accommodation: Operating a large format digital camera and a laser scanning system simultaneously needs an aircraft with two holes in the fuselage. High weight and power consumption might need use of a large (and thus more expensive) aircraft. Survey height: It has to be taken into account that large format digital cameras have a fixed field of view (FOV), which means that a certain survey height stands for a certain ground sampling distance and swath width.

5) combined with a horizontal 360° rotation of the whole instrument. 21) allows generation of a field of view which is basically only limited by self-occlusions of the instrument itself and its tripod. 1 discussed the advantages and disadvantages of different range measurement principles: direct time-of-flight measurement delivers a larger range capacity, while phase-measurement based CW systems provide better accuracy and a higher data rate. Time-of-flight measurement is clearly dominant in airborne laser scanner systems, which are usually employed at flying altitudes between 200 m and 4000 m.

G. snow in the visible wavelength range). A return echo coming from a low reflecting target will have a lower amplitude compared to that from a high reflecting target. Due to this fact, simple pulse detectors in time-of-flight systems tend to put out longer ranges for low reflecting targets. As a consequence, for instance, white markings on a dark asphalt runway will hover above the runway in a range image if this effect is not corrected. Correction may be done with help of tables providing time (= range) corrections for low reflecting targets or by the use of constant-fraction detection techniques.
