Description
The Points Thinning tool aggregates points at a level that fits the specified resolution. The information of those points that become aggregated is based on basic statistics, i.e. mean values for coordinates and mean, minimum, maximum, standard deviation for the selected attribute. Due to the underlying spatial structure the quadtree and the raster method lead to differing, though comparable results.
