detailed LiDAR production workflow using LAStools, FME, GDAL, FUSION, ...

[Martin Isenburg]

Hello,

One of our long-time users, the folks from the GIS department of the government of La Rioja, Spain ("Sección de Sistemas de Información Geográfica y Cartografía") have published exact details (in both English and Spanish language) of their implementation of a methodology for obtaining classified LiDAR files and the subsequent production of Digital Terrain Models (DTMs) using LAStools from rapidlasso, FME from Safe Software, as well as GDAL and FUSION. You can read about the command lines and download the scripts / workbench that were used here.

HI.

I am a beginner when it comes to LIDAR processing so these kinds of tutorials are very helpful to me. Thank you for taking the time to publish them.  I do have one question though.

It seems like most of what I read on this mailing list is only applicable to people who use windows. I downloaded the LASTools archive to my linux machine and followed the instructions to make the binaries and I only got a handful of the binaries mentioned in the various posts on this email list.  I really don't want to boot into windows just for this task so I am curious to see if there are linux binaries for the rest of the stack someplace.

Thanks.

Hello Tim.

on linux or MacOS wine is your friend. It seems to work quite well even in HPC environments as you can read in these discussion threads here:

Tim,

I can confirm that wine does work to process with LAStools on linux. The back-end processing for the NOAA Digital Coast Data Access Viewer is all on RHEL7 and uses LAStools for creation of DEM via TIN and for creation of contours, plus a few other things. It does that by calling wine. Note that your pain level depends a bit on the Linux distro you're using. RHEL7 is 64-bit and the doesn't come naturally with the wine libraries to run 32-bit windows, which all the LAStools are. Other distros may be more forgiving, but RHEL7 has extra steps required.
