Fast Google Polyline encoding and decoding using Rust FFI
Project description
Installation
pip install pypolyline Please use a recent (>= 8.1.2) version of pip.
Supported Python Versions
Python 2.7 Python 3.5
Supported Platforms
Linux (manylinux1-compatible)
OS X
Windows 32-bit / 64-bit
Usage
from pypolyline.util import encode_coordinates, decode_polyline
coords = [
[52.64125, 23.70162],
[52.64938, 23.70154],
[52.64957, 23.68546],
[52.64122, 23.68549],
[52.64125, 23.70162]
]
# precision is 5 for Google Polyline, 6 for OSRM / Valhalla
polyline = encode_coordinates(coords, 5)
# polyline is 'ynh`IcftoCyq@Ne@ncBds@EEycB'
decoded_coords = decode_polyline(polyline, 5)Attempts to decode an invalid Polyline will throw util.DecodingError
Attempts to encode invalid coordinates will throw util.EncodingError
How it Works
