polyline

A simple google-esque polyline implementation in Javascript. Compatible with nodejs (npm install @mapbox/polyline and the browser (copy src/polyline.js)).

Encodes from / decodes into [lat, lng] coordinate pairs. Use fromGeoJSON() to encode from GeoJSON objects, or toGeoJSON to decode to a GeoJSON LineString.

Installation

npm install @mapbox/polyline

Note that the old package polyline has been deprecated in favor of @mapbox/polyline (the old package remain but won't receive updates).

Example

1var polyline = require('@mapbox/polyline');
2
3// returns an array of lat, lon pairs
4polyline.decode('_p~iF~ps|U_ulLnnqC_mqNvxq`@');
5
6// returns an array of lat, lon pairs from polyline6 by passing a precision parameter
7polyline.decode('cxl_cBqwvnS|Dy@ogFyxmAf`IsnA|CjFzCsHluD_k@hi@ljL', 6);
8
9// returns a GeoJSON LineString Geometry
10polyline.toGeoJSON('_p~iF~ps|U_ulLnnqC_mqNvxq`@');
11
12// returns a string-encoded polyline (from coordinate ordered lat,lng)
13polyline.encode([[38.5, -120.2], [40.7, -120.95], [43.252, -126.453]]);
14
15// returns a string-encoded polyline from a GeoJSON LineString
16polyline.fromGeoJSON({ "type": "Feature",
17  "geometry": {
18    "type": "LineString",
19    "coordinates": [[-120.2, 38.5], [-120.95, 40.7], [-126.453, 43.252]]
20  },
21  "properties": {}
22});
