Processing the data from an entire (or by file) flight to geolocate a quick image. All done using a Linux Mint 18 live USB stick on the Panasonic Toughbook CF-54 and external USB3 drives.

Inputs:

• Real time Applanix trajectory
• Shot data from LVIS

• To compile programs, you need to install this package on the linux mint live I am using

  sudo apt-get install libc6-dev

• For g++ I ended up doing

  sudo apt-get update
  sudo apt install g++

Using the program applanixraw2out.c to convert the raw binary data to our .out format.

• Concatenate all of the raw data into a single binary file

  cat /media/mint/LVIS_RED002/57927/B200T_N44U/imu/610i_0341/* > /media/mint/RABINE_2015_BACKUP/tmp/applanixraw57927.bin

• Extract just the trajectory information
  • Compile the code

    cd /home/mint/code/applanix
    gcc applanixraw2out.c -o applanixraw2out

  • Run on the raw data

    ./applanixraw2out /media/mint/RABINE_2015_BACKUP/tmp/applanixraw57927.bin

  • Move and rename the trajectory

    mv applanix_raw_traj.out /media/mint/RABINE_2015_BACKUP/tmp/applanix57927_20170623.out

Turn an entire flight of data into a single binary file we can geolocate.

• Change the code so that it appends to a file rather than overwriting it
  • Change this

    fpout = fopen(argv[2],"wb");

  • To this

    fpout = fopen(argv[2],"ab");

• Compile the code

  g++ lvisfile2quicklook.c xmcParseMeta.cpp -o lvisfile2quicklook

• Create this shell script to run it
  • Make a file name runme
    • Edit the file

      nano runme

    • Put this in the file

      #!/bin/bash
      
      for file in $1/lvis_*.dat
      do
         echo "Processing file $file..."
         ~/code/lvis2quicklook/lvisfile2quicklook $file /media/mint/RABINE_2015_BACKUP/tmp/lvisquicklook.dat
      done

  • Change the permissions so you can run it

    chmod 755 runme

• Run the script, and it will dump all the data into a single file

  time ./runme /media/mint/LVIS_RED002/57927/B200T_N44U/rtlvis/
