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.
|
|
|
|
For Windows all binaries are included. All open source tools can be compiled
|
|
from the source code. For MSVC6.0 there is a project file. For Linux and MacOS
|
|
the makefiles are included. Simply go into the root directory and run 'make':
|
|
|
|
unzip LAStools.zip
|
|
cd LAStools/
|
|
make
|
|
|
|
The compiled binary executables are or will be in the ./LAStools/bin directory.

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.
