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 andContinue Reading

is a tool that reads LIDAR from LAS/LAZ/ASCII and grids them onto a raster. The most important parameter ‘-step n’ specifies the n x n area that of LiDAR points that are gridded on one raster cell (or pixel). The output is either in BIL, ASC, IMG, TIF, PNG, JPG,Continue Reading

is a tool that reads LIDAR points and colors them using an ortho image provided in TIF format. The output is a standard LAS or a compressed LAZ file where each points has an RGB color sampled from the ortho photo. Instead of LiDAR points the tool – like all LAStools – canContinue Reading

is a tool that reads LIDAR points from LAS/LAZ/ASCII (or rasters from ASC/BIL/DTM format) and extracts a set of particular elevation contours in SHP/KML/WKT/TXT format. The user may specify to extract contours every 5 meters or only for individual elevation values. The contours can be smoothed or simplified on demand and hydro breaklines can beContinue Reading

is a tool that triangulates LIDAR points from the LAS/LAZ format (or some ASCII format) into a temporary TIN and then rasters the TIN to create a DEM. The tool can either raster the ‘-elevation’, the ‘-slope’, the ‘-intensity’, the ‘-rgb’ values, or a ‘-hillshade’ or ‘-gray’ or ‘-false’ coloring.Continue Reading

is a tool to classify buildings and high vegetation (i.e. trees) in LAS/LAZ files. This tool requires that the bare-earth points have already been identified (e.g. with lasground) and that the elevation of each point above the ground was already computed with lasheight (which stores a coarse height value inContinue Reading

is a tool for bare-earth extraction: it classifies the LiDAR points into ground points (class = 2) and non-ground points (class = 1). The tools works very well in natural environments such as mountains, forests, fields, hills, and even steep terrain but also gives excellent results in towns or cities.Continue Reading

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. WhenContinue Reading

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.Continue Reading
