time-aware-polyline

Time aware polylines in javascript

The google encoded polyline algorithm converts location coordinates into an ascii string. We have extended the algorithm to convert location coordinates with time stamps into ascii strings. The time aware polyline is also available in python.

Time aware polylines can be used to mark time events on polylines, or run a trip replay, like in the HyperTrack dashboard.

Install

$ npm i time-aware-polyline

Encoder

var polylineUtil = require('time-aware-polyline');
 
var points = [
    [19.13626, 72.92506, '2016-07-21T05:43:09+00:00'],
    [19.13597, 72.92495, '2016-07-21T05:43:15+00:00'],
    [19.13553, 72.92469, '2016-07-21T05:43:21+00:00']
]
polylineUtil.encodeTimeAwarePolyline(points);

Decoder

var polylineUtil = require('time-aware-polyline');
 
var polyline = 'spxsBsdb|Lymo`qvAx@TKvAr@K';
polylineUtil.decodeTimeAwarePolyline(polyline);
