// 地址解析器 根据经纬度获取当前车辆所在地址

由于键盘上没有 ° 键,所以我在程镇樱序中把它换成 * 键了。
运行下面御派丛程序,从控制台输入 40582974 ,回车 ,输出结果:22*32.7658′
若
输入:57335948
则
输出:31*51.1983'
import java.math.BigDecimal;
import java.util.Scanner;
public class LatitudeTransform {
public static void main(String[] args) {
Scanner sca = new Scanner(System.in);
String in = sca.nextLine();
//将控制台接收到的输入转成数字
long num = Long.parseLong(in);
//利用整除舍弃余数得到度数值
long du = (num / 30000) / 60;
//将控制台接收到的数值除以30000,得到度和分的混合结果,再对60取余,得到分的部分
BigDecimal fen = new BigDecimal(num).divide(new BigDecimal(30000), 4, BigDecimal.ROUND_HALF_UP).remainder(
new BigDecimal(60));
System.out.println(du + "*" + fen + "'");
}
}
下面的部分是,在控制台输入22°32.7658′ ,回车得到40582974。开始的时候读你的问题理解反了,所以先写的这个,也给你吧,要是没用就算了~呵呵。
import java.util.Scanner;
public class LatitudeTransform {
public static void main(String[] args) {
Scanner sca = new Scanner(System.in);
String in = sca.nextLine();
String result = transform(in);
System.out.println(result);
}
private static String transform(String in) {
/羡烂/将输入的字符串分成两截,分别为度数du_string,分数fen_string
String du_string = in.substring(0, in.indexOf("*"));
//substring方法两个参数遵循规则"前包含后不包含",例,”1234“.substring(0,2)返回的结果是index为0到1的子串,即"12"
String fen_string = in.substring(in.indexOf("*") + 1, in.indexOf("'"));
double du = Double.parseDouble(du_string);
double fen = Double.parseDouble(fen_string);
Long result = (long) ((du * 60 + fen) * 30000);
return result.toString();
}
}
range = 180 / PI * 1 / 6372.797; //里面的 1 就代表搜索 1km 之内,单位坦大km
lngR = range / Math.cos(myLat * PI / 180);
maxLat =myLat + range;//最大纬度
minLat = myLat - range;//最圆判小纬度
maxLng = myLng + lngR;//最大经度
minLng = myLng - lngR;//最小经度橘信改
类型全部是double
还有一种估算方法
请参考
