comparison between models with different discretization

Two models with different discretization are compared here. To the left (discretization to 10 cm) one can see that the survey grid is much larger than the case shown on the right (discretization to 2 cm.) making it possible to provide a more detailed model of the paving altimetry.
As may be seen from the examples shown, the three-dimensional model discretized to 2 cm provides a much more accurate picture of the altimetric profile of the paving than the model discretized to10 cm.
