高德地图现在使用比较多了，但是高德地图计算两点之间的距离有些问题。下面提供一个很好的解决方案。

代码如下：

/**

* 两点的经纬度获取两点距离米

* @param (121.293986,37.279148,121.284545,37.292396)

* @returns {string}

* @author zhangyufeng

*/

$rootScope.getGDDTDistance = function (startlongitude,startdimensionality,endlongitude,enddimensionality) {

var lon1 = (Math.PI / 180) * startlongitude;

var lon2 = (Math.PI / 180) * endlongitude;

var lat1 = (Math.PI / 180) * startdimensionality;

var lat2 = (Math.PI / 180) * enddimensionality;

// 地球半径

var R = 6371;

// 两点间距离 km，如果想要米的话，结果*1000就可以了

var d = Math.acos(Math.sin(lat1) * Math.sin(lat2) + Math.cos(lat1) * Math.cos(lat2) * Math.cos(lon2 - lon1)) * R;

return d * 1000;

};

/**

* 获取距离

* @param distance

* @returns {string}

* @author lixiang

*/

$rootScope.getDistance = function (distance) {

if(distance==null){

return "";

}

var meter = 'm';

var kilometer = 'km';

var result = '';

if (distance < 1000) {

result = distance.toFixed(0) + meter;

} else {

var km = distance / 1000;

if (km >= 100) {

//超过100公里 去掉小数点

result = (distance / 1000).toFixed(0) + kilometer;

} else if(km >= 10){

//10-100公里以内 1位小数

result = (distance / 1000).toFixed(1) + kilometer;

} else {

//10公里以内 2位小数

result = (distance / 1000).toFixed(2) + kilometer;

}

}

return result;

};

前台调用 {{getDistance(getGDDTDistance(121.293986,37.279148,121.284545,37.292396))}}

public class Distribution

{

// 经度

double longitude;

// 维度

double dimensionality;

public double getLongitude()

{

return longitude;

}

public void setLongitude(double longitude)

{

this.longitude = longitude;

}

public double getDimensionality()

{

return dimensionality;

}

public void setDimensionality(double dimensionality)

{

this.dimensionality = dimensionality;

}

/*

* 计算两点之间距离

*

* @param start

*

* @param end

*

* @return 米

*/

public double getDistance(Distribution start, Distribution end)

{

double lon1 = (Math.PI / 180) * start.longitude;

double lon2 = (Math.PI / 180) * end.longitude;

double lat1 = (Math.PI / 180) * start.dimensionality;

double lat2 = (Math.PI / 180) * end.dimensionality;

// double Lat1r = (Math.PI/180)*(gp1.getLatitudeE6()/1E6);

// double Lat2r = (Math.PI/180)*(gp2.getLatitudeE6()/1E6);

// double Lon1r = (Math.PI/180)*(gp1.getLongitudeE6()/1E6);

// double Lon2r = (Math.PI/180)*(gp2.getLongitudeE6()/1E6);

// 地球半径

double R = 6371;

// 两点间距离 km，如果想要米的话，结果*1000就可以了

double d = Math.acos(Math.sin(lat1) * Math.sin(lat2) + Math.cos(lat1) * Math.cos(lat2) * Math.cos(lon2 - lon1)) * R;

return d * 1000;

}

}
