Introduction ¶

A Python implementation of Google’s Encoded Polyline Algorithm Format (http://goo.gl/PvXf8Y). This is essentially a port of https://github.com/mapbox/polyline built with Python 2 and 3 support in mind.

polyline can be installed using pip or easy_install:

$ pip install polyline
or
$ easy_install polyline

To get the encoded polyline representation of a given set of coordinates:

from polyline import PolylineCodec
PolylineCodec().encode([(38.5, -120.2), (40.7, -120.9), (43.2, -126.4)])

This should return _p~iF~ps|U_ulL~ugC_hgN~eq`@.

To get the set of coordinates reprented by a given encoded polyline string:

from polyline import PolylineCodec
PolylineCodec().decode('u{~vFvyys@fS]')

This should return [(40.63179, -8.65708), (40.62855, -8.65693)].
