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
- 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)
- if you have a directory full of las files to classify, cd into it and paste the following:
mkdir classified_las counter=1 for lasfile in *LAS ; do echo $counter $lasfile las_single_class.py -i $lasfile -o classified_las/$lasfile -c $counter counter=$(( $counter + 1)) done
- Load into FugroViewer
- Colour points by classification (settings menu -> point color -> classification)
