Separation.js
Calculate the distance between 2 coordinates or check whether 2 coordinates are within a given range. Supports distance and range in miles, meters, and kilometers.
Based on the Haversine formula.
Features
- Find the distance between 2 coordinates
- Check whether 2 coordinates are within a given range
- (WIP) Fetch coordinates within a given range
Installation
$ npm i separation
Usage
This is how you can use it in your code.
const separation = require('separation');
//coordinates must be objects with these keys:
//(lat or latitude) and (lon, lng or longitude)
let c1 = { lat:13.7565, lng:13.76765 },
c2 = { latitude: 12.2321, lon: 12.2345 }
//find the distance between 2 coordinates
let distance = separation.distance(c1, c2, "km"); //gets result in km (default)
let distance_in_miles = separation.distance(c1, c2, "mi"); //gets result in miles
let distance_in_meters = separation.distance(c1, c2, "m"); //gets result in meters
//check if 2 coordinates are within a range.
//returns the distance if they are within the given range, otherwise returns false
let nearby = separation.isNearby(c1, c2, 5, "km");
