polyline
polyline is a Python implementation of Google's Encoded Polyline Algorithm
Format (http://goo.gl/PvXf8Y). It is essentially a port of
https://github.com/mapbox/polyline built with Python 2 and 3 support in mind.
Installation
polyline can be installed using pip or easy_install:
$ pip install polyline or $ easy_install polyline
API Documentation
Encoding
To get the encoded polyline representation of a given set of (lat, lon) coordinates:
import polyline polyline.encode([(38.5, -120.2), (40.7, -120.9), (43.2, -126.4)], 5)
This should return _p~iF~ps|U_ulL~ugC_hgN~eq`@.
You can set the required precision with the optional precision parameter. The default value is 5.
You can encode (lon, lat) tuples by setting geojson=True.
Decoding
To get a set of coordinates represented by a given encoded polyline string:
import polyline
polyline.decode('u{~vFvyys@fS]', 5)
This should return [(40.63179, -8.65708), (40.62855, -8.65693)] in (lat, lon) order.
You can set the required precision with the optional precision parameter. The default value is 5.
You can decode into (lon, lat) tuples by setting geojson=True.
