same direction. Correspondingly, biases were 6-8 cm and
standard deviations +4-6 em for the flight strips to the opposite
directions. To summarize, the planimetric accuracy is worse
than vertical but acceptable for various purposes.
The first pulse mode observations tend to exaggerate the area
and the lengths of the roofs. The first pulse data give about 11-
14 % larger building roofs than the last pulse data. Lengths of
the roofs were about 21 cm longer from the first pulse data than
in reality. Correspondingly, the last pulse mode gives
underestimated results. Lengths were about 25 cm smaller than
the obtained reference measurements. These systematic effects
have to be realized e.g. in cartographic applications.
