A simple library to parse IGC logs and extract thermals.

Uses ground speed to detect flight and aircraft bearing rate of change to detect thermalling. Both are smoothed using the Viterbi algorithm.

The code has been battle-tested against a couple hundred thousand IGC files. Detects various anomalies in the logs and marks files as suspicious/invalid, providing an explaination for the decision. If you find an IGC file on which the library misbehaves please open a GitHub issue, we'd be happy to investigate.

Example usage:

  python igc_lib_demo.py some_file.igc

Should work both on Python 2.7 and on Python 3.
