    33The RCD produces raw files that need to be processed in order to create TIFF files.  The processing basically uses a gain and offset scaling and (probably) corrects for lens distortion.  See the [wiki:Sensors/RCD_CH39 RCD page] for more details, including filename convention.

    2832If you are lucky you should be able to do the whole processing chain through running one script. To improve the chances of this working follow the stages below to set up the data and remove as many anomalies as possible.
     
    4650 * SBET file GPS times do not overlap with photograph log file times. Either fix the SBET (if possible) else use the logfile to tag the images (and mention in the Read_Me)

    5356tifftagger2_exiftool is a python script that uses the exiftool command line tool too add tags to a tiff. It draws this data from an image event file. In addition to the data in the image event file the user can use several arguments to supplement the information. the -s option allows the gps location to be read from the given sbet file and is recommend if an sbet is available.

    7881Only minimal tagging can be performed: original filename, project code, flight day and site name. This is because without the timestamp of the image event we cannot match up any navigation information. Ask mark1 for a clunky script to do this (will get updated to a better script soon).
     
    8083Renaming the files can take place once they have been tagged with the original filename information. Ask mark1 for a clunky script to do this (will get updated to a better script soon).

     85=== Creating Thumbnails ===
    8386
    8487We need to create thumbnail images for the delivery and for getting an overview of the images for the checking procedure. To do this use the photo2thumb.sh script.
