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: arsf_winesetup.sh

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

(untested)

• Add a different classification number to each LAS file, using knpa's classification utility:
  • run las_single_class.py -i INPUTNAME -o OUTPUTNAME -c CLASSIFICATION_NUMBER (classifications can be 0-255)
• Load into FugroViewer
• Color points by classification
