All programs run in an windows environment. On request we can provide also Linux binaries of some tools.
All tools are 32 bit versions by default. Some tools has also a 64 bit version. This versions have a ending “64” in the filename.
The full download has a size of about 80 MB.
This is always the newest version.
If you need other versions or just some parts of the tools check the https://github.com/LAStools/LAStools.github.io repository.
The software is delivered as a ZIP file. Download the latest version as shown above.
Unzip the files into a directory on your local harddisk.
Put your licence file into the ./bin directory.
Open a command line (e.g. “Start” > “Execute” > “cmd” or “Start” > “cmd”).
Go to the ./bin directory and run a LAStool command.
If you want you can use the Graphical User Interface (GUI) of some tools. Most users prefer the command line.
If you unzipped the files to “c:\lastools” your first commands could look like this:
c: cd \lastools\bin laszip -i ../data/lake.laz -o ../data/lake.las
This will convert the sample file “lake.laz” to the uncompressed file “lake.las” in the sample data directory.
It is most likely that you use scripts (batch files) to do your work. A sample script “do_my_work.cmd” could look like this:
:: this is a comment line :: this is the second line of my sample :: extend the path to find the LAStools binaries (just for this script) set path=C:\lasools\bin;%path% :: be lazy, set some variables set "ddir=C:\data" set "odir=%ddir%\out" set "sdir=c:\lastools\data" :: do some magic las2las -i %sdir%\lake.laz -o %odir%\out1.laz -set_version 1.3 -set_point_type 3 -v las2las64 -i %odir%\out1.laz -o %odir%\out2.laz -drop_class 1 7 -set_RGB 222 44 55 -v pause
To view the content of a LAS/LAZ file you may use our tool LASview:
lasview -i lake.laz
To get a first overview about the tools see the overview page in this webpage.
To get information about a certain tool see the readme files within the bin directory or use the -h parameter to show the parameters in the terminal. To get deeper information about a command or a certain questionary see the google group and enter your question into the search field. Also you can download the full tutorial PDF and do a full text search there.
Don’t get confused about the versions we provide. The version numbers following this syntax:
Year[YY]Month[MM]Day[DD] of the release. So Version 211206 means, the version was released at 6th of December in 2021.
You may do not need the newest version. As long as your version is doing what you want your are fine. If there are important updates they will be announced in the google group. Usually the new versions contain all what we have posted in the LAStools google group since last release. It is wise to be a member there and read the mails posted there. To see the changes of a new version you may have a look at the CHANGES.txt file within the ZIP file of the delivery.
The licensed version always contain also the current version of the OpenSource parts.
It is not necessary to download or update the OpenSource part separate.
If you are not sure which version you are using:
In Windows just execute one of the executables like “lasdatum.exe”. The GUI will show the version number at bottom left. On a command line just type the executable name followed by -h: This will output the help of the program and will usually also show the version number:
> lasdatum -h ... LAStools (by firstname.lastname@example.org) version 210720 (...) ...
