函数: distance()

distance(from: Coord, to: Coord, options?: { units?: Units; }): number

Function

Calculates the distance between two coordinates in degrees, radians, miles, or kilometers. This uses the Haversine formula

to account for global curvature.

参数

from

Coord

origin coordinate

to

Coord

destination coordinate

options?

Optional parameters

units?

Units

Supports all valid Turf Units

.

返回

number

distance between the two coordinates

示例

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;
