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]') This should return ``[(40.63179, -8.65708), (40.62855, -8.65693)]`` in (lat, lon) order.
