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
Feature<Point> origin pointto
Feature<Point> destination pointunits
[String] can be degrees, radians, miles, or kilometers (optional, defaultkilometers
)
Examples
var from = "type": "Feature" "properties": {} "geometry": "type": "Point" "coordinates": -75343 39984 ;var to = "type": "Feature" "properties": {} "geometry": "type": "Point" "coordinates": -75534 39123 ;var units = "miles"; var points = "type": "FeatureCollection" "features": from to; //=points var distance = turf; //=distance
Returns Number distance between the two points
