laspublishcreates a LiDAR portal for 3D visualization (and optionally also for downloading) of LAS and LAZ files in any modern Web browser.
demdiffcompares rasters in ASC, BIL, TIF, IMG and RasterLAZ format and reports differences.
demzipcompresses and uncompresses raster data from ASC, BIL, TIF, IMG format to the compressed RasterLAZ format.
las2shpconverts LIDAR from LAS/LAZ/ASCII to ESRI's Shapefile format by grouping consecutive points into MultiPointZ records.
shp2lasconverts from points from ESRI's Shapefile to LAS/LAZ/ASCII format given the input contains Points or MultiPoints.
las2tinreads LIDAR data in LAS/LAZ/ASCII format and creates a TIN.
lascopythis tool copies selected attributes from LiDAR points from a source to a target LAS/LAZ file using the GPS-time stamp and the return number as a reference.
lasdatumtransforms LiDAR from one horizontal datum to another using either a NTv2 grid or a seven parameter helmert transform.
lasvdatumtransforms LiDAR from ellipsoidal to orthometric elevations using a grid in format that is usually provided by the national survey and expresses the vertical differences between some geoidal model and some elliptical model of the earth.
lasdiffcompares the LIDAR data of two LAS/LAZ/ASCII files and reports whether they are identical or whether they are different.
lasdistancethis tool classifies, flags, or removes LiDAR points based on their approximate xy distance from polygonal segments.
laslayersenhance the LAS/LAZ format with layers.
lasplanesfinds sufficiently planar patches of LAS/LAZ points fulfilling a number of user-defineable criteria that are output as simple polygons to SHP or RIEGL's PEF format.
lasprecisionreads LIDAR data in the LAS format and computes statistics that tell us whether the precision "advertised" in the header is really in the data.
lasprobethis 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 product BLAST is an extension of the LAStools toolset. It is the ultimate speed up to utilizes unique “streaming TIN” technology to seamlessly triangulate billions of points for subsequent rasterization into a DEM with blast2dem or extraction of elevation contours with blast2iso.

Our product PulseWave is an open source effort for a vendor-neutral exchange format for geo-referenced full waveform LiDAR called PulseWaves. The format is similar to the ASPRS LAS standard, but instead of storing discrete returns, it stores geo-referenced laser pulses and those parts of the outgoing and returning waveforms that were digitized. The source code and the specification of the PulseWaves format have been released under the terms of the LGPL (version 2.1) on github.
