python-flexpolyline-pbapi 0.1.1

Flexible Polyline encoding (PBAPI extension)

FlexPolyline and HERE Polyline

This is a fork of the python implementation of the Flexible Polyline format. It has been developed to support the HERE polyline encoding used by HERE Places (Search) API for the compressedRoute requests parameter.

Use the original repo heremaps/flexible-polyline if you only need to encode/decode polylines used in HERE Geocoding & Search API or HERE Routing API.

Install

$ pip install python-flexpolyline-pbapi

Usage

>>> encode(iterable, pbapi=True)

Encodes a list (or iterator) of coordinates to the corresponding HERE polyline string representation. Coordinate order is (lat, lng[, width]).

>>> decode(polyline_string, pbapi=True)

Decodes a HERE polyline string into an array of coordinates (lat, lng[, width]).

Note that width is expected to be one of DW, HW, CW.

Examples

import flexpolyline_pbapi as fp

example = [
    (50.1022829, 8.6982122),
    (50.1020076, 8.6956695),
    (50.1006313, 8.6914960),
    (50.0987800, 8.6875156),
]

print(fp.encode(example, pbapi=True))

Output: oz5xJ67i1B1B7PzIhaxL7Y.

import flexpolyline_pbapi as fp

print(fp.dict_decode("oz5xJ67i1B.C1B7PzIha.DxL7Y", pbapi=True))

Output:

[
    (50.10228, 8.69821, 'CW'), 
    (50.10201, 8.69567), 
    (50.10063, 8.6915, 'DW')
]
