Rowland Johnson developed an excellent tool, DatCon, for analyzing DJI Phantom 3 log files in Java. I arranged to have it ported to Python because I am far more adept with Python and wanted something that I could extend to support newer file formats and potentially other UAVs.
The result can be found here:
It is my hope that others will build on this, adding support for other DJI products as well as adding visualization capabilities.
Feedback, suggestions, etc are always welcome.
