JAVA获取多个经纬度的中心点
import java.util.LinkedList; public class Test1 { /** * 位置实体类,根据自己的来即可 */ static class Position{ /** * 纬度 */ private Double latitude; /** * 经度 */ private Double longitude; public Double getLatitude() { return latitude; } public void setLatitude(Double latitude) { this.latitude = latitude; } public Double getLongitude() { return longitude; } public void setLongitude(Double longitude) { this.longitude = longitude; } public Position(Double latitude, Double longitude) { this.latitude = latitude; this.longitude = longitude; } } /** * 取几个经纬度的中心点 * @param postionList 经纬度的集合 */ public static void getCenterPoint(LinkedList<Position> postionList) { int total = postionList.size(); double X = 0, Y = 0, Z = 0; while(!postionList.isEmpty()) { Position g = postionList.pollFirst(); if(g != null) { double lat, lon, x, y, z; lat = g.getLatitude() * Math.PI / 180; lon = g.getLongitude() * Math.PI / 180; x = Math.cos(lat) * Math.cos(lon); y = Math.cos(lat) * Math.sin(lon); z = Math.sin(lat); X += x; Y += y; Z += z; } } X = X / total; Y = Y / total; Z = Z / total; double Lon = Math.atan2(Y, X); double Hyp = Math.sqrt(X * X + Y * Y); double Lat = Math.atan2(Z, Hyp); double longitude = Lon * 180 / Math.PI; double latitude = Lat * 180 / Math.PI; System.out.println("中心点经度:"+longitude); System.out.println("中心点纬度:"+latitude); } public static void main(String[] args) { LinkedList<Position> list=new LinkedList<>(); list.add(new Position(35.1719916700000040,119.2328202000000200)); list.add(new Position(35.1319216700000040,119.2925302000000200)); list.add(new Position(35.1919216700000040,119.2625302000000200)); getCenterPoint(list); } }
