LIDAR processing in Linux

The main LIDAR processing software is all Windows based, but parts can be run under the WINE windows emulator in Linux. The parts that work are:

  • ALS Post Processor
  • FugroViewer (LAS file viewer)

Bentley Microstation (and thus TerraScan) currently do not work under WINE. This functionality can be partially replaced by..[work tbd!]

Set up

To set this up, do the following under your own userid:

You can now run the ALS PP with alspp.exe and the FugroViewer with fugroviewer.exe

General operation

This is the same as the normal processing procedure.

CAUTION: The C: drive you'll see in wine will be stored in your homespace on the RSG disk - if this fills up, everything breaks and you buy beer for the whole group! Please save files to your normal scratch space.

Workarounds for Bentley functionality

Differentiating flightlines by color

  • Add a different classification number to each LAS file, using knpa's classification utility:
    • run -i INPUTNAME -o OUTPUTNAME -c CLASSIFICATION_NUMBER (classifications can be 0-255)
    • if you have a directory full of las files to classify, cd into it and paste the following:
      mkdir classified_las
      for lasfile in *LAS ; do
         echo $counter $lasfile -i $lasfile -o classified_las/$lasfile -c $counter
         counter=$(( $counter + 1))
  • Load into FugroViewer
  • Colour points by classification (settings menu -> point color -> classification)
