Time aware polylines in python

The google encoded polyline algorithm converts location coordinates into an ascii string. We have extended the algorithm to convert location coordinates with time stamps into ascii strings. The time aware polyline is also available in javascript.

Time aware polylines can be used to mark time events on polylines, or run a trip replay, like in the HyperTrack dashboard.

Install

pip install time_aware_polyline

Encoder

from time_aware_polyline import encode_time_aware_polyline

points = [
    [19.13626, 72.92506, '2016-07-21T05:43:09+00:00'],
    [19.13597, 72.92495, '2016-07-21T05:43:15+00:00'],
    [19.13553, 72.92469, '2016-07-21T05:43:21+00:00'],
]

encoded = encode_time_aware_polyline(points)

Decoder

from time_aware_polyline import decode_time_aware_polyline

polyline = 'spxsBsdb|Lymo`qvAx@TKvAr@K'

decoded = decode_time_aware_polyline(polyline)

Testing

To run the tests, you will need to install pytest.

pip install pytest

For running the tests, run the following command.

py.test
