haversine-offset

Haversine offset formula in Javascript. Uses meters. Nothing more.

Example

Offset is in meters, x is along the longitudinal axis (East / West), y along the latitudinal axis (North / South).

var haversineOffset = require('haversine-offset')
 
var a = { latitude: -37.8136, longitude: 144.9631 }
var offset = { x: 100, y: 150 }
 
console.log(haversineOffset(a, offset))
// { lat: -37.812252527073824, lng: 144.96423709426978 },

lat, lng variants will also work:

var haversineOffset = require('haversine-offset')
 
var a = { lat: -37.8136, lng: 144.9631 }
var offset = { x: 100, y: 150 }
 
console.log(haversineOffset(a, offset))
// { lat: -37.812252527073824, lng: 144.96423709426978 },
