trajectory
trajectory is a library for lossy compression of trajectory data based on Google’s Encoded Polyline Algorithm Format (http://goo.gl/PvXf8Y). It is heavily based on (in fact forked from) https://github.com/hicsail/polyline.
Installation
trajectory can be installed using pip or easy_install
$ pip install trajectory
or
$ easy_install trajectoryAPI Documentation
Encoding
To serialize a trajectory (set of (lat, lon, unix time in seconds) tuples)
import trajectory
trajectory.encode([
(38.500, -120.200, 1582482601),
(40.700, -120.950, 1582482611),
(43.252, -126.453, 1582482627)
], 5)This should return _p~iF~ps|U_ynpijgz~G_ulLnnqC_c`|@_mqNvxq`@__t`B.
You can set the required precision with the optional precision parameter. The default value is 5.
Decoding
To deserialize a trajectory (set of (lat, lon, unix time in seconds) tuples) represented by an encoded string
import trajectory
trajectory.decode('_p~iF~ps|U_ynpijgz~G_ulLnnqC_c`|@_mqNvxq`@__t`B', 5)This should return the following:
[
(38.500, -120.200, 1582482601),
(40.700, -120.950, 1582482611),
(43.252, -126.453, 1582482627)
