## Requirements

* A bunch of images (jpg, cr2, etc.) with its time of creation stored in `DateTimeOriginal`.

* GeigerCounter log file in csv format as it is being exported by the software GeigerLog.

* Optionally a GPX (1.0 / 1.1) track that has been recorded during the same timeperiod.

All sources are matched by their timestamp, so all sources have to be recorded during the same time (and timezone). The Geiger counter has to log a value every second, as the script compares the timestamps exactly.

## GPS setup
|

|

Especially if you use a mobile phone for GPS-logging. Take care, the app can use GPS when turned off, and let it write position sufficiently often. Threshold is 5 minutes by default, but precision will improve when logging more often. Especially "inactivity detection" might become a problem, when staying at one place for a period of time.
