Owl Processing Guide

The Owl thermal hyperspectral sensor is new to the arsf and does not yet have a complete processing chain. As this is developed this wiki page will be updated. Details on the Owl sensor are available here and information on Owl testing is available here.

Radiometric Calibration

Specim have provided a tool to process the Owl raw data into calibrated data. Details on using this tool are located here if required.

To batch process the data use: processOWL.py -p <project directory>

To process individual lines use: process_OWL_line.py -p <project directory> -f <flightline>

Each flightline should have it's own calibration data in the form of additional files prefixed T1 and T2 in the capture directory. If these are not present the script will produce a warning. Run the script again with the option -c auto once the submitted flightlines have produced the required calibration files (Check the log has passed the "Writing calibration file..." step), or manually specify a calibration file with -c <flightline with calibration data_calibration.rad>.

All output files are written to the /processing/owl/calibration subdirectory of the project folder and logs written to /processing/owl/logs. The output files consist of the data (*_proc.data) and if not specified as inputs, the calibration (*_calibration.rad) and blinker files (*blinkers.dat), all with their own header file. Intermediate files are stored in /users/rsg/airborne/workspace/Owl/ and deleted on completion.
