(The program txt2las.exe converts LIDAR data from standard ASCII in various formattings to binary LAS format (version 1.2). The corresponding las2txt.exe turns binary LAS into human-readable and easy-to-parse textual representations. The tool lasinfo.exe prints out a quick overview of the contents of a LAS file, las2shp.exe turns binary LAS into ESRI s Shapefile format, shp2las.exe turns an ESRI s Shapefile into binary LAS, lasmerge.exe can merge several LAS files into one, las2las.exe allows extracting only last returns, only points within a bounding box, etc., lasthin.exe implements a simple point thinning algorithm, las2tin.exe triangulates the points of a LAS file into a TIN, las2dem.exe rasterizes them into a DEM, las2iso.exe extracts, optionally simplified, elevation contours, and lasboundary.exe computes a boundary polygon (i.e. a concave hull of the points). The little OpenGL viewer lasview.exe visualizes the contents of a LAS file and can also compute a TIN. It needs the GLUT32)

LAStools - converting, viewing, and compressing LIDAR data in LAS format
latest update: http://www.cs.unc.edu/~isenburg/lastools/
* txt2las.exe converts LIDAR data from ASCII text to binary LAS format
* las2txt.exe turns LAS into human-readable and easy-to-parse ASCII text
* lasinfo.exe prints out a quick overview of the contents of a LAS file
* las2shp.exe turns binary LAS into ESRI's Shapefile format
* shp2las.exe turns an ESRI's Shapefile into binary LAS
* lasmerge.exe can merge several LAS files into one
* las2las.exe extracts only last returns, clips, subsamples, etc ...
* lasthin.exe implements a simple point thinning algorithm
* las2tin.exe triangulates the points of a LAS file into a TIN
* las2dem.exe rasterizes them into a DEM
* las2iso.exe extracts, optionally simplified, elevation contours
* lasview.exe visualizes the contents of a LAS file.
For Windows all binaries are included. They can also be compiled from
the sources. You can find the MSVC6.0 project files there as well.
For Linux all Makefiles and sources are included. Simply go into the
main directory and run 'make'.
unzip lastools.zip
cd lastools/
make
The (pre-)compiled binary executables are (will be) in the ./bin directory.
--------------------------------------------
LASreader and LASwriter
This is the API for reading and writing LAS files from and to the
standard format (*.las) as defined by (www.lasformat.org) as well
from and to our compressed format (*.laz).
We include the sources (./src) for the LASreader and LASwriter
classes. However, we do not (yet) include the source for the
compressor. For the moment the compressor is only accessible
through function calls to the Windows libs.
---------------------------------------------

suggestions, or if you want to license these tools, please email me.
