Manual RCD processing/delivery stages

Tagging images which have camera log files

Tag_tiffs.py 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 (this should be the processed event file from IPAS CO). In addition to the data in the image event file the user can use several arguments to supplement the information. For information on the script use the -h option

tag_tiffs.py -V -d dd/mm/yyyy -p <projcode> -l <sitename> ( -s sortie ) <eventfile> <photographs_directory>

where:

dd/mm/yyyy is the date the image data was collected

sortie is the flight letter (e.g a, b, etc)

to check the changes use exiftool.

exiftool /users/rsg/arsf/arsf_data/2010/flight_data/iceland/IPY09_11-2009_219_Helheim/leica/rcd/proc_images/07120958100001G4.tif 

A second script is used to then rename the files with useful names containing the project code, year and day. this script also takes the processed image events file and the folder containing the images as arguments, renames the files and creates a new image events file with the file names updated.

for more information on the script use -h option

rename_photos_update_events_file.py -v -d dd/mm/yyyy -c <projcode> ( -s sortie ) <eventfile> <photographs_directory>

Tagging images which do not have camera log files

Only 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).

Renaming 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).

Creating a kml file

Create a KML file for the delivery, using the eventfile created using rename_photos_update_events_file.py above

generateKMLforPI.py -d <main_project_dir> -e <eventfile> -o <kml_output_filename>

Creating thumbnails

We 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.

Example:

photo2thumb.sh -d proc_images -o proc_thumbnails

Will create JPG thumbnails of all the TIF images in the proc_images directory and save them into a directory called thumbnails. For further usage run photo2thumb.sh -h

Creating delivery structure

Once the data has been processed, it needs to be put into a delivery directory. This is the final file structure in which it will be sent to the customer. Delivery directory structure ¶ The delivery layout is detailed here and you can copy the directory template from /users/rsg/arsf/arsf_data/2011/delivery/camera/template/
