Preliminary tests of the potential advantages of combining laser 
scanner and GPS surveying fully justify the use of this method. 
The precision obtained in the recording procedures and the 
direct analysis of the complete model have demonstrated its 
good reliability. 
At the moment, we are conducting a study to evaluate the 
precision of the model and to assess the applicability of the 
method to larger portions of a territory. 
Use of the survey for cartographic or cadastral purposes can be 
hypothesized on the basis of the results of the restitution tests.
