NUM (NUMVIS)

During the rasterization process, a horizontal grid is applied to the original Dense Cloud, leading to the grid cells receiving exactly one point, if data is available. The NUM images capture in the horizontal grid the number of points detected for each cell in the initial Dense Cloud. The NUMVIS images refer to the same information, but the values initially stored in NUM are scaled, for visualization purposes.
