This experiment was meant to determine which method is better in the term of fastness, optimization and speed of processing the data. We analyzed a site with both methods: the classical topographical survey and a 3D scanning laser measurement, with a focused idea on to the second technique. The area which we survey lies in the city of Iasi and represents a thermal local power station. We tried to respect the same technical parameters for both techniques. In the end we came to the conclusion that the 3D laser scanning we used matches the application, in this case civil engineering, but, in Romania, the authorities and the legal situation are not yet prepared to accept that.
