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
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,
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 – can
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 be
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.
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 in
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.
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
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.
