Unreleased#

🚀 Added#

  • function turn_rate for calculating how fast the aircraft is turning, in degrees per kilometre, and the matching Survey.turn_rate method.

  • function split_at_turns for splitting flights into lines wherever the aircraft turns, and the matching Survey.split_at_turns method.

  • split_into_segments can now split existing lines via segment_column, naming the new sub-lines by extending the existing names (i.e. 12 -> 12, 12_1).

  • absolute option in split_into_segments to split on decreases as well as increases.

  • method Survey.plot_intersections for mapping crossover errors.

  • method Survey.estimate_error_wavelength for estimating the along-line wavelength of levelling error.

  • Survey.line_sampling_rates and Survey.median_sampling_rates statistics, now shown in Survey.describe().

  • line option in Survey.plot to plot a single line.

  • column_name option in Survey.along_track_distance, which sets the survey’s distance column.

  • plot_profiles now supports up to 4 y axes and a title per axis, and colors an axis to match its series if it only holds one.

✏️ Changed#

  • alternating_iterative_line_levelling now levels the tie lines before the flight lines.

  • plot_line_and_crosses now defaults to plot_inters=True.

  • Survey.plot_profiles now requires a line and plots only that line.

  • Survey.split_into_segments now splits each existing line on its own, if the line column exists.

  • split_into_segments returns string names when segment_column is given.

  • Survey now warns if supplied column names are not in the dataframe.

  • Survey.median_line_spacings is computed on every 2nd point, for speed.

  • Survey.describe() formats values to 3 significant figures, with units.

🐛 Fixed#

  • fixed filter_line failing on repeated coordinates (e.g. duplicated timestamps).

  • fixed level_to_grid ignoring groupby_column when assigning corrections.

  • fixed plot_levelling_convergence failing for runs which converged on their first iteration.

  • fixed plot_line_and_crosses failing when intersections haven’t been added to the data.
