Filtering by place

It 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 function timeVideoNormalize, 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.

import trackanimation
from trackanimation.animation import AnimationTrack

input_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 indicator

Furthermore, 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.

import trackanimation
from trackanimation.animation import AnimationTrack

input_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 map
fig = AnimationTrack(df_points=ibiza_trk, dpi=300, bg_map=False, map_transparency=0.5)
fig.make_map(output_file='coloring-map-by-speed')

Visualizing multiple set of tracks

Multiple sets of tracks can be plotted independently in the same visualization to compare them.

import trackanimation
from trackanimation.animation import AnimationTrack

input_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')
