Photo mosaic from the video camera system of the Noppikoski dam in Sweden. This day it was snowing and the ground is snow cowered with 5 cm of wet snow. There was very bad weather and thick clouds. This gives a bad contrast of the area. Single pixel resolution is about 5 cm. The two groves on top of the dam is the wheels from a car which just passed the damm. The width between the wheela are about 1,7 meter.

Bottom image

Side view of the dam with one point per laser shot. Distance is corresponding to infinity and this is a orto view from the side. At left there are trees and detections on ground and up in the tree are easily noticed. On the bottom there is the rock face under the damm. Totally there are over 60 000 points in this image. Accuracy in global coordinates is about +- 1-2 meter as we used a low priced DGPS and simple inertial navigation during this job. Customer demands was making this OK.
