This software is work in progress. Currently, it seems to be working in first tests, but it is lacking a lot of checks and functions. THIS IS NOT READY NOT FOR PRODUCTIVE USE.
A simple command line gpx correlator for photos, similar to gpscorrelate.
gpscorrelate is fine, but I decided to write my own correlator in order to add functions, namely
- correlating additional gpx tags, such as temperature or heart rate,
- adding place names,
- reading multiple gpx files, e.g. parallel recordings from different devices, and map to the closest trackpoint over all files,
- spline interpolation (planned) and perhaps even estimation of directions,
- whatever seems useful and can be implemented with reasonable effort.
Complete list of dependencies:
- Linux OS or similar
- Python3.x
- evix2 command line version
For a quick start, I decided to use exiv2 for modifying exif tags. I may move to pyexiv later.
python3 gpxcorrelate [-v] [tz=<hours>] [to=<seconds>] [comment=<clear|append>] [place=<true|false>] <gpxfiles> -- <imagefiles>
- tz: timezone +- 12 hours
- to: time offset in seconds
- place: if true, request a place name from the OSM Nominatim geocoding API. This code respects the restrictions stated at https://operations.osmfoundation.org/policies/nominatim/.
gpxcorrelate.py place=true tag=atemp comment=append ~/GPS/Tracks/*.gpx -- *
Correlate all files in the current directory using all GPX files in ~/GPS/Tracks, using my local timezone. If possible, add a place name from the google maps API to the UserComment EXIF field. When available, also add the temperature value from the XML tag atemp to the UserComment.
