由于键盘上没有 ° 键，所以我在程序中把它换成 * 键了。
运行下面程序，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) {
//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();
}
}
定一个原点。 定一个比例尺 然后根据点与原点的距离，得到坐标，再通过与原点的坐标比，得到距离，再转成经纬度
记得我前几天发过一个类似的代码如下（适用安卓）
import android.app.Activity;
import android.os.Bundle;
import android.location.*;
import android.content.*;
import android.util.Log;
import android.widget.TextView;
public class GPSLocationListenActivity extends Activity implements LocationListener {

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
locman = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
}
@Override
protected void onResume(){
if (locman != null){
locman.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,0,this);
}
super.onResume();
}
@Override
protected void onPause(){
if (locman != null){
locman.removeUpdates(this);
}
super.onPause();
}
@Override
public void onLocationChanged(Location location){
TextView textView1 = (TextView)findViewById(R.id.textView1);
textView1.setText("Latitude:Longitude - "
+String.valueOf(location.getLatitude()) +":"+String.valueOf(location.getLongitude()));
TextView textView2 = (TextView)findViewById(R.id.textView2);
textView2.setText(String.valueOf(location.getTime()));
Log.v("----------", "----------");
Log.v("Latitude", String.valueOf(location.getLatitude()));
Log.v("Longitude", String.valueOf(location.getLongitude()));
Log.v("Accuracy", String.valueOf(location.getAccuracy()));
Log.v("Altitude", String.valueOf(location.getAltitude()));
Log.v("Time", String.valueOf(location.getTime()));
Log.v("Speed", String.valueOf(location.getSpeed()));
Log.v("Bearing", String.valueOf(location.getBearing()));
}
@Override

}
@Override
