Point cloud index point

point_count

This index counts all points within the ROI.

Note that a LiDAR laser pulse may result in multiple return points which are all counted by this index.

point_coverage

ratio of area that is covered by LiDAR points (based on 1x1 meter pixel raster, if in one pixel is no point, pixel is not covered)

Query area is divided in 1x1 meter areas. One area is covered if at least one point is contained.

point_coverage := covered_areas_count / areas_count

point_density

density of LiDAR points (points per m² in bounding box)

point_elevation_max

highest point a.s.l.

point_elevation_mean

mean of points a.s.l.

point_elevation_min

lowest point a.s.l.

point_elevation_sd

standard deviation of points a.s.l.
