Package: trackanimation
Track Animationis a Python 2 and 3 library that provides an easy and user-adjustable way ofcreating visualizations from GPS dataeasily and without any kind of technical tie for the user. It allows to import GPS data fromGPX(GPS eXchange Format) and CSV files in order to manipulate it and, finally, createvideos,images, sequences of images orinteractive mapsto analyze the tracks based on their elevation, speed, duration or any other indicator.The main third party libraries thatTrack Animationuses aregpxpyto parse and read GPX files,pandasto manipulate all the GPS data andmatplotlibto plot it and save the visualizations.To create a basic visualization, simply read the files and pass them to theAnimationTrackclass:importtrackanimationfromtrackanimation.animationimportAnimationTrackinput_directory="example-routes/"ibiza_trk=trackanimation.read_track(input_directory)fig=AnimationTrack(df_points=ibiza_trk,dpi=300,bg_map=True,map_transparency=0.5)fig.make_video(output_file='simple-example',framerate=60,linewidth=1.0)DependenciesgpxpypandasmatplotlibgeopysmopymplleafletpillowtqdmFFmpegInstallationInstallTrack Animationusingpipwith:pip install trackanimationOr,download the source files from PyPI.Getting StartedYou can find the following examples in theexamples.pyfile.Filtering by placeIt is possible to filter a set of tracks to retrieve only the points that belong to an specific place or the whole tracks that have passed by there. With the functiontimeVideoNormalize, all the tracks will start and end at the same time in the video, specyfing its duration and frame rate in the parameters. In the next example, the video created has a duration of 10 seconds with 10 frames per second.importtrackanimationfromtrackanimation.animationimportAnimationTrackinput_directory="example-routes/"ibiza_trk=trackanimation.read_track(input_directory)sant_josep_trk=ibiza_trk.get_tracks_by_place('Sant Josep de sa Talaia',only_points=False)sant_josep_trk=sant_josep_trk.time_video_normalize(time=10,framerate=10)fig=AnimationTrack(df_points=sant_josep_trk,dpi=300,bg_map=True,map_transparency=0.5)fig.make_video(output_file='filtering-by-place',framerate=10,linewidth=1.0)Coloring tracks by one indicatorFurthermore, an indicator of the tracks can be visualized as a palette of colors to make the analysis and the interpretation of the data easier and effective.importtrackanimationfromtrackanimation.animationimportAnimationTrackinput_directory="example-routes/ibiza.csv"ibiza_trk=trackanimation.read_track(input_directory)ibiza_trk=ibiza_trk.time_video_normalize(time=10,framerate=10)ibiza_trk=ibiza_trk.set_colors('Speed',individual_tracks=True)fig=AnimationTrack(df_points=ibiza_trk,dpi=300,bg_map=True,map_transparency=0.5)fig.make_video(output_file='coloring-map-by-speed',framerate=10,linewidth=1.0)# Variable 'bg_map' must be to False in order to create an interactive mapfig=AnimationTrack(df_points=ibiza_trk,dpi=300,bg_map=False,map_transparency=0.5)fig.make_map(output_file='coloring-map-by-speed')Click to view the interactive mapVisualizing multiple set of tracksMultiple sets of tracks can be plotted independently in the same visualization to compare them.importtrackanimationfromtrackanimation.animationimportAnimationTrackinput_directory="example-routes/"ibiza_trk=trackanimation.read_track(input_directory)sant_josep_trk=ibiza_trk.get_tracks_by_place('Sant Josep de sa Talaia',only_points=False)ibiza_trk=ibiza_trk.set_colors('Speed',individual_tracks=True)sant_josep_trk=sant_josep_trk.set_colors('Speed',individual_tracks=True)fig=AnimationTrack(df_points=[ibiza_trk,sant_josep_trk],dpi=300,bg_map=True,map_transparency=0.5)fig.make_image(output_file='multiple-axes')DocumentationMore documentation and examples can be found atTrack Animation PDF document.
