track(data, *, latitude_column, longitude_column, groupby_column=None, ellipsoid=True)[source]#

Calculate the track between each successive row in a dataframe. Track is the angle from geographic north (positive clockwise) that and aircraft travels over the ground. This is different to the heading or bearing, which is the angle the nose of the plane points, which is affected by wind. If groupby_column is provided, the dataframe will first be grouped by this.

Parameters:

  • data (DataFrame) – Dataframe containing the data points and must have columns ‘easting’ and ‘northing’.

  • groupby_column (str | None) – Column name to group by before calculation, by default None

  • latitude_column (str)

  • longitude_column (str)

  • ellipsoid (bool)

Returns:

The track in degrees, in the range 0 to 360, positive clockwise from geographic north

Return type:

Series
