@turf/distance

distance

Calculates the distance between two points in degrees, radians, miles, or kilometers. This uses the Haversine formula to account for global curvature.

Parameters

from Coord origin point
to Coord destination point
options Object Optional parameters (optional, default {})
- options.units string can be degrees, radians, miles, or kilometers (optional, default 'kilometers')

Examples

var from = turf.point([-75.343, 39.984]);
var to = turf.point([-75.534, 39.123]);
var options = {units: 'miles'};

var distance = turf.distance(from, to, options);

//addToMap
var addToMap = [from, to];
from.properties.distance = distance;
to.properties.distance = distance;

Returns number distance between the two points
