radiation tagger

exif_rad.py is a simple unix-style cross-platform Python 3 tool which can write certain tags to an image file.

It can scan a couple of images, extract their Exif-tags, and compare the DateTimeOriginal with other sources.

By now it can parse a .his (CSV) file from a GeigerLog file export and calculate the radiation in µS/h using the factor in SIFACTOR.

It then creates a UserComment Exif tag with the actual measured radiation at the time the photo has been taken.

Dependencies

Right now it depends on the following Python 3 libraries:

• PIL (core library)
• datetime (core library)
• Image (core library)
• piexif
• gpxpy

Requirements

• GeigerCounter log file in csv format as it is being exported by the software GeigerLog. Such files look like this: 149654, 2020-02-27 05:12:42, 13.0, 0.0
• A bunch of images (jpg, cr2, etc.) with its time of creation stored in DateTimeOriginal
• A gpx track

All sources are matched by their timestamp, so all sources have to be recorded during the same time.

Usage

to-do

future possibilities

• In the future it should also be able to do the same with a gpx-file to extract geolocations and to write them into the appropiate Exif-fields.
• It might get interactive help and command line argument processing.
• It might get a setup.py if I want to waste my time on it.
• I might want to get rid of the requirement to use a bloated GUI application to download the history data off the geigercounter. There must be a neat working command line tool.
