geodesy-fn

Geodesic functions for GeoJSON, based on geodesy.

Compared to geodesy, this library exports geodesic calculations as light-weight functions. The input/output is GeoJSON.Position = [longitude, latitude].

Currently implemented functions from geodesy:

• spherical
  • distance
  • initialBearing
  • finalBearing
  • midpoint
  • destinationPoint

More functions from geodesy can be added as needed.

Install

npm install geodesy-fn

Usage

import { distance } from 'geodesy-fn/src/spherical';

const p1 = [0.119, 52.205];
const p2 = [2.351, 48.857];
const d = distance(p1, p2);
