    55== Owl Pre-Processing Checks==
    66
    7 Before processing, or as part of unpacking, the following checks are recommended:
     7These are normally done as part of unpacking.
    88
    991) Check for dark frames. From the top level directory run:
    10 
     10{{{
    1111grep -rnw thermal/owl/*/capture/*.hdr -e "autodarkstartline"
    12 
     12}}}
    1313Data cannot be processed without this keyword, so ensure that it is listed for each flightline. If dark frames are missing they can be added following instructions in the Dark Frames section.
    1414
    15152) Check for nav synchronisation:
    16 
     16{{{
    1717grep -rnw thermal/owl/*/capture/*.hdr -e "GPS"
    18 
     18}}}
    1919If there are no GPS times in the data header, the data cannot be geocorrected. Use owl_hdr_fix.py to add the times from the file modification time and check it is reasonable.
    2020
    21213) Check for calibration data:
    22 
     22{{{
    2323ls thermal/owl/*/capture/T1* [[BR]]
    2424ls thermal/owl/*/capture/T2* [[BR]]
    25 
     25}}}
    2626Make sure that there is at least 1 T1 and 1 T2 file present for the flight and that it is located in the same directory as the flight data. If there are double the number of expected flightlines, then the calibration data is probably stored in separate directories from the flight data. The unpacking scripts should move the raw data into ordered number flightline directories and the T1 and T2 files into directories labelled by time.

    56 Specim have provided a tool to process the Owl raw data into calibrated data.  Details on using this tool are located [https://arsf-dan.nerc.ac.uk/trac/wiki/Procedures/OwlProcessing/OwlTool here] if required.

    58 To batch process the data use: batch_cal_owl_proctool.py  -p <project directory>
    59 
    60 To process individual lines use: cal_owl_proctool.py -p <project directory> -f <flightline>

    6266Use the -s flag if the raw files did not have dark frames and have been stitched into the processing/owl/flightlines/stitched directory.
