LAStools: award-winning software for efficient LiDAR processing (with LASzip)

You find all individual LAStools in the .\LAStools\bin directory. Start
them by double-clicking or run them in the DOS command line. The ArcGIS
toolbox can be found in .\LAStools\ArcGIS_toolbox and the QGIS toolbox
in .\LAStools\QGIS_toolbox. A few example DOS batch scripts can be found
in the .\LAStools\example_batch_scripts directory.

open source tools:

* laszip.exe compresses the LAS files in a completely lossless manner
* lasinfo.exe prints out a quick overview of the contents of a LAS file
* lasindex.exe creates a spatial index LAX file for fast spatial queries
* las2las.exe extracts last returns, clips, subsamples, translates, etc ...
* lasmerge.exe merges several LAS or LAZ files into a single LAS or LAZ file
* txt2las.exe converts LIDAR data from ASCII text to binary LAS format
* las2txt.exe turns LAS into human-readable and easy-to-parse ASCII
* lasprecision.exe analyses the actual precision of the LIDAR points

closed source tools:

* lastool.exe is an old GUI for multiple LAStools (now each tool has its own GUI)

* lasground.exe extracts the bare-earth by classifying all ground points
* lasground_new.exe an improved version of lasground.exe for complex terrains
* lasoverlap.exe checks overlap & vertical/horizontal alignment of flight lines
* lascontrol.exe quality checks elevations for a list of control points
* lasclassify.exe finds buildings and the vegetation above the ground
* lascolor.exe colors the LAS points based on ortho imagery in TIF format
* lasgrid.exe grids onto min/max/avg/std elevation, intensity, or counter rasters
* lascanopy.exe computes many raster and plot metrics for forestry applications
* lasboundary.exe extracts a boundary polygon that encloses the points
* lasheight.exe computes for each point its height above the ground
* lastrack.exe classifies LiDAR point based on distance from a trajectory
* lasplanes.exe finds planar patches in terrestrial, mobile, (airborne?) scans
* lasclip.exe clips points against building footprints / swath boundaries
* lastile.exe tiles huge amounts of LAS points into square tiles
* lassplit.exe splits points of LAS file(s) into flightlines or other criteria
* lassort.exe sorts points by gps_time, point_source, or into spatial proximity
* lasduplicate.exe removes duplicate points (with identical x and y, z optional)
* lasthin.exe thins lowest / highest / random LAS points via a grid
* las2tin.exe triangulates the points of a LAS file into a TIN
* las2dem.exe rasters (via a TIN) into elevation/slope/intensity/rgb DEMs
* las2iso.exe extracts, optionally simplified, elevation contours
* lasview.exe visualizes a LAS file with a simple OpenGL viewer
* las2shp.exe turns binary LAS into ESRI's Shapefile format
* shp2las.exe turns an ESRI's Shapefile into binary LAS

BLAST extension

* blast2dem.exe rasters like las2dem but with streaming TINs for billions of points.
* blast2iso.exe contours like las2iso but with streaming TINs for billions of points.

Please read the "LICENSE.txt" file for information on the legal use and licensing
of LAStools. I would also really like it if you would send me an email and tell me
what you use LAStools for and what features and improvements you could need.
