= LIDAR processing in Linux = The main LIDAR processing software is all Windows based, but parts can be run under [http://www.winehq.com/ 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 [wiki:Processing 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 the classified files into FugroViewer * Colour points by classification (settings menu -> point color -> classification)
