This tool probes the elevation of the LIDAR for a given x and y location and reports it to a text file or to stdout. The tool reads LIDAR in LAS/LAZ/ASCII format, triangulates the relevant points into a TIN. For classified data sets containing a mix of ground and vegetation/building points it is imperative to …
Add layer functionality to LAS/LAZ files. 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 …
A simple open source tool with LGPL 2.1 license to validate whether a single or a folder of LAS or LAZ files conform to the LAS specification of the ASPRS. If something goes wrong during your LiDAR processing with LAStools it is good to run a lasvalidate check before asking a question in the LAStools user forum as the validation report will …
is a simple yet fast LiDAR visualization tool that has a number of neat little tricks that may surprise you. It can also edit the classification of the points as well as delete them. For more details see the README file. 2021-10-22

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 …
reads LAS or LAZ files containing points from multi-return LiDAR systems and either reports return statistics, find and marks sets of points from the same laser shots that are incomplete (i.e. missing returns), or repairs the ‘number of returns’ field based on GPS times. Note that input files need to be sorted based on their GPS …
is a tool that reads LIDAR points from LAS/LAZ or ASCII files and computes the flight line overlap and / or the vertical and horizontal alignment. The output rasters can either be a color coded visual illustration of the level of overlap or the differences or the actual values and can be either in BIL, …
