This is a handy tool to report the contents of the header, the VLRs, and a short summary of the min and max values of the points for LAS/LAZ files. The tool warns when there is a difference between the header information and the point content for counters and bounding box extent. When you send us a support […]

Creates a LiDAR portal for 3D visualization (and optionally also for downloading) of LAS and LAZ files in any modern Web browser using the WebGL Potree from Markus Schuetz. See README file for more information.

Transforms LiDAR from ellipsoidal to orthometric elevations using a grid in format that is usually provided by the national survey and expresses the vertical differences between some geoidal model and some elliptical model of the earth. By default the conversion is from ellipsoidal elevations to geoidal (or orthometric) elevations. If you want to go theother

reads LIDAR data in the LAS format and computes statistics that tell us whether the precision “advertised” in the header is really in the data. Often I find that the scaling factors of a LAS/LAZ file is miss-leading because they make it appear as if there was much more precision than there really is. To

This tool classifies, flags, or removes LiDAR points based on their approximate xy distance from polygonal segments. This distance is calculated on a grid with a spacing of 0.5 meters by default. With ‘-step_xy 1.0’ the granularity of this grid can be adjusted up or down. Please license from before using lasdistance commercially. Please

compares the LIDAR data of two LAS/LAZ/ASCII files and reports whether they are identical or whether they are different. See README file for more information.

Transforms LiDAR from one horizontal datum to another using either a NTv2 grid or a seven parameter helmert transform. Note that there are two ways of specifying the rotational part of the Helmert transform. The Position Vector Transformation (PVR) convention and the Coordinate Frame Rotation (CFR) convention.The difference between them is that their rotation matrix

This tool copies selected attributes from LiDAR points from a source to a target LAS/LAZ file using the GPS-time stamp and the return number as a reference. By default the selected attributes of the source points are copied to all target points if the two share the exact samecombination of GPS-time stamp and return number.

This tool flags or removes noise points in LAS/LAZ/BIN/ASCII files. The tool looks for isolated points according to certain criteria that can be modified via ‘-step 3’ and ‘-isolated 3’ as needed. The default for step is 4 and for isolated is 5. It is possible to specify the xy and the z size of

is a tool that splits LAS or LAZ files into multiple files based on some criteria. By default it splits the points into separate files based on the ‘point source ID’ field that usually contains the flightline ID. Others options are The last of these simply splits the input into chunks of 1000000 points. One
