哈弗辛公式在大多数情况下都是很好的公式，其他答案已经包含了它所以我就不占用空间了。但重要的是要注意，无论使用什么公式(是的，不仅仅是一个)。因为可能的精度范围很大，以及所需的计算时间。公式的选择需要更多的思考，而不是简单的无脑答案。

这个帖子来自nasa的一个人，是我在讨论这些选项时发现的最好的一个

http://www.cs.nyu.edu/visual/home/proj/tiger/gisfaq.html

例如，如果您只是在100英里半径内按距离对行进行排序。地平公式比哈弗辛公式快得多。

HalfPi = 1.5707963;
R = 3956; /* the radius gives you the measurement unit*/

a = HalfPi - latoriginrad;
b = HalfPi - latdestrad;
u = a * a + b * b;
v = - 2 * a * b * cos(longdestrad - longoriginrad);
c = sqrt(abs(u + v));
return R * c;

注意这里只有一个余弦和一个平方根。在哈弗辛公式中有9个。

下面是Haversine公式的typescript实现

static getDistanceFromLatLonInKm(lat1: number, lon1: number, lat2: number, lon2: number): number {
    var deg2Rad = deg => {
        return deg * Math.PI / 180;
    }

    var r = 6371; // Radius of the earth in km
    var dLat = deg2Rad(lat2 - lat1);   
    var dLon = deg2Rad(lon2 - lon1);
    var a =
        Math.sin(dLat / 2) * Math.sin(dLat / 2) +
        Math.cos(deg2Rad(lat1)) * Math.cos(deg2Rad(lat2)) *
        Math.sin(dLon / 2) * Math.sin(dLon / 2);
    var c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));
    var d = r * c; // Distance in km
    return d;
}

下面是移植到Java的已接受的答案实现，以备任何人需要。

package com.project529.garage.util;


/**
 * Mean radius.
 */
private static double EARTH_RADIUS = 6371;

/**
 * Returns the distance between two sets of latitudes and longitudes in meters.
 * <p/>
 * Based from the following JavaScript SO answer:
 * http://stackoverflow.com/questions/27928/calculate-distance-between-two-latitude-longitude-points-haversine-formula,
 * which is based on https://en.wikipedia.org/wiki/Haversine_formula (error rate: ~0.55%).
 */
public double getDistanceBetween(double lat1, double lon1, double lat2, double lon2) {
    double dLat = toRadians(lat2 - lat1);
    double dLon = toRadians(lon2 - lon1);

    double a = Math.sin(dLat / 2) * Math.sin(dLat / 2) +
            Math.cos(toRadians(lat1)) * Math.cos(toRadians(lat2)) *
                    Math.sin(dLon / 2) * Math.sin(dLon / 2);
    double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));
    double d = EARTH_RADIUS * c;

    return d;
}

public double toRadians(double degrees) {
    return degrees * (Math.PI / 180);
}

这是我的java实现计算距离经过一些搜索。我用的是世界平均半径(来自维基百科)，单位是千米。İf你想要的结果英里，然后使用世界半径英里。

public static double distanceLatLong2(double lat1, double lng1, double lat2, double lng2) 
{
  double earthRadius = 6371.0d; // KM: use mile here if you want mile result

  double dLat = toRadian(lat2 - lat1);
  double dLng = toRadian(lng2 - lng1);

  double a = Math.pow(Math.sin(dLat/2), 2)  + 
          Math.cos(toRadian(lat1)) * Math.cos(toRadian(lat2)) * 
          Math.pow(Math.sin(dLng/2), 2);

  double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));

  return earthRadius * c; // returns result kilometers
}

public static double toRadian(double degrees) 
{
  return (degrees * Math.PI) / 180.0d;
}

function getDistanceFromLatLonInKm(lat1,lon1,lat2,lon2,units) {
  var R = 6371; // Radius of the earth in km
  var dLat = deg2rad(lat2-lat1);  // deg2rad below
  var dLon = deg2rad(lon2-lon1); 
  var a = 
    Math.sin(dLat/2) * Math.sin(dLat/2) +
    Math.cos(deg2rad(lat1)) * Math.cos(deg2rad(lat2)) * 
    Math.sin(dLon/2) * Math.sin(dLon/2)
    ; 
  var c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a)); 
  var d = R * c; 
  var miles = d / 1.609344; 

if ( units == 'km' ) {  
return d; 
 } else {
return miles;
}}

查克的解决方案，也适用于英里。

对于那些寻找基于WGS-84和GRS-80标准的Excel公式的人:

=ACOS(COS(RADIANS(90-Lat1))*COS(RADIANS(90-Lat2))+SIN(RADIANS(90-Lat1))*SIN(RADIANS(90-Lat2))*COS(RADIANS(Long1-Long2)))*6371
