geocircle v1.0.0

Geo Circle

This is a lightweight geo utility package that can extract all of the latitude and longitude coordinates within an array of data within a user-defined km circle area

Installation

Installation is with npm : npm install geocircle --save

Usage

To get started, create a GeoCircle object and pass it the correct parameters. In your array of data you need to have a LatLng object of anatomy { lat: 34.0001, lng: -33.1111 } by default the key latlng is used but you can specify a user-defined key for example coords as the fourth argument to the GeoCircle constructor.

const GeoCircle = require('geocircle');

const data = [
    {
        name: "A",
        coords: { //we'll specify the key 'coords' to target this object that holds the lat/lng
            lat: 52.000,
            lng: -33.500
        }
    },
    {
        name: "B",
        coords: {
            lat: -34.9285,
            lng: 138.6007
        }
    }
];

var geoCircle = new GeoCircle(52.000, -33.000, data, 'coords'); //note the use of the key 'coords'
geoCircle.setGeoCircleWithin(100) //within 100km
console.log(geoCircle.toString()) // name: A | Latitude: 52.00000 | Longitude: -33.50000
