lasintensity

This tool corrects the intensity attenuation due to atmospheric absorption. Because the light has to travel longer distances for points with large scan angles, these points may be detected with reduced intensities. In order to get a reliant attenuation estimate several parameters are essential: As the absorption coefficient may be difficult to grasp, lasintensity implements …

las3dpoly

As an input take, for example, a LAS/LAZ/TXT file and a SHP/TXT file with oneor many polylines (e.g. powerlines).This feature modifies points within a certain distance of those polylines.There are two separate options for running point selection; you can either: Affected points can be classified, clipped, or flaged. The input SHP/TXT file must contain clean …

lascolor

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

lasvalidate

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 …

lasprobe

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 …

lascontrol

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 …

lasreturn

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 …

lasoverlap

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, …

lasinfo

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 …
