distance

描述

¥Description

计算两个 coordinates 之间的距离（以度、弧度、英里或公里为单位）。本模块使用 半正矢公式 来计算全局曲率。

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

参数

¥Parameters

名称	类型	描述
from	坐标系	原点坐标
to	坐标系	目标坐标
options?	对象	可选参数（默认值：）
options.units?	单位	支持所有有效的 Turf 单位。(默认 'kilometers')

返回

¥Returns

number 两者之间的距离坐标

¥number distance between the two coordinates

示例

¥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);

安装

¥Installation

$ npm install @turf/distance

import { distance } from "@turf/distance";
const result = distance(...);

$ npm install @turf/turf

import * as turf from "@turf/turf";
const result = turf.distance(...);
