Package Exports
- polyline
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (polyline) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
polyline
A simple google-esque polyline
implementation in Javascript. Compatible with nodejs (npm install polyline and the browser (copy src/polyline.js)).
Encodes/decodes into lat/lng coordinate pairs. Use fromGeoJSON() to encode from GeoJSON objects.
Installation
npm install polylineExample
var polyline = require('polyline');
// returns an array of lat, lon pairs
polyline.decode('_p~iF~ps|U_ulLnnqC_mqNvxq`@');
// returns a string-encoded polyline
polyline.encode([[38.5, -120.2], [40.7, -120.95], [43.252, -126.453]]);
// returns a string-encoded polyline from a GeoJSON LineString
polyline.fromGeoJSON({ "type": "Feature",
"geometry": {
"type": "LineString",
"coordinates": [[-120.2, 38.5], [-120.95, 40.7], [-126.453, 43.252]]
},
