java计算二个经纬度间的距离(百度坐标)
1:背景
工作中遇到计算二个地点之间的距离,根据百度经纬度进行计算。
2:maven 依赖
<dependency> <groupId>org.gavaghan</groupId> <artifactId>geodesy</artifactId> <version>1.1.3</version> </dependency>
3:代码实现
package com.pacific.transfer.util;
import org.gavaghan.geodesy.Ellipsoid;
import org.gavaghan.geodesy.GeodeticCalculator;
import org.gavaghan.geodesy.GeodeticCurve;
import org.gavaghan.geodesy.GlobalCoordinates;
/**
* 经纬度计算方法
*/
public class CaculateDistanceTest {
public static void main(String[] args) {
GlobalCoordinates source = new GlobalCoordinates(31.258934000000, 121.595511000000);
GlobalCoordinates target = new GlobalCoordinates(31.235124000000, 121.530746000000);
double meter1 = getDistanceMeter(source, target, Ellipsoid.Sphere);
double meter2 = getDistanceMeter(source, target, Ellipsoid.WGS84);
System.out.println("Sphere 坐标系计算结果:" + meter1 + "米");
System.out.println("WGS84 坐标系计算结果:" + meter2 + "米");
}
/**
* 计算距离
*
* @param from
* @param to
* @param ellipsoid
* @return
*/
public static double getDistanceMeter(GlobalCoordinates from, GlobalCoordinates to, Ellipsoid ellipsoid) {
// 经纬度计算距离
GeodeticCurve geoCurve = new GeodeticCalculator().calculateGeodeticCurve(ellipsoid, from, to);
return geoCurve.getEllipsoidalDistance();
}
}
4:结果如下:
Sphere 坐标系计算结果:6701.987620282907米
WGS84 坐标系计算结果:6710.41999653924米
