@thisisbarney/track-layer

a track layer, displaying tracks of vehicles, derived from PathLayer.

import React from 'react';
import TrackLayer from '@thisisbarney/track-layer';

const layers = [
  new TrackLayer({
    // parameters same with PathLayer
    id: 'points',
    data,
    // different
    trailLength: 300,
    getWidth: d => 10,
    getPath: d => d.path,
    currentTime: time,
    maxSpeed: 5,
  })
];

Key parameters different from PathLayer is getPath and curentTime, getPath maps a data row to a path consists of [x, y, time], currentTime corresponds with time in path.

trailLength defines the length of each track, maxSpeed is used to filter out invalid(too fast) points, getWidth allows to pass a mapping to control each track's width.
