computes the elevation of the LiDAR at certain x and y control point locations and reports the difference in respect to the control point elevation. The tool reads LiDAR in LAS/LAZ/ASCII format, triangulates the relevant points around the control points into a TIN. For classified data sets containing a mix of ground and vegetation/building points it is imperative to specify the points against which the elevation measurements are to be taken (i.e. usually ‘-keep_class 2 8’). For more details see the README file.
