... with highly accurate DEM from ground light detection and ranging (LiDAR) measurements. This study also employs probability and statistical analysis of rockfall simulations to deal with uncertainties such as the coefficients of restitution, slope friction, and the location and velocity of where the rocks...

.... In one hand, this amount of data is in constant evolution and, in the other hand, the user discovers new data applications. However, for a geographic database, the duality processing delays/amount of data does not satisfy the user according to his needs of multi-scale restitution...
