How to find the degree of latitude value in android?

Question

I have latitude and longitude as double value (37.33168900, -122.03073100).

I want to convert it to a degree value similar to (37 19 '54, 48 11 '52).

Any idea? Thanx in advance.

Answer 1

Must be math:

(int)37.33168 => 37 37.33168 % 1 = 0.33168 0.33168 * 60 = 19,905 => 19 19.905 % 1 = 0.905 0.905 * 60 => 54 

same with -122 (add 360 if nagative value)

EDIT: Maybe there is an API that I don't know.

Answer 2

This will give you lines in degrees, minutes and seconds of arc:

 String strLongitude = location.convert(location.getLongitude(), location.FORMAT_SECONDS); String strLatitude = location.convert(location.getLatitude(), location.FORMAT_SECONDS); 

.

Answer 3

use this

 public static String getFormattedLocationInDegree(double latitude, double longitude) { try { int latSeconds = (int) Math.round(latitude * 3600); int latDegrees = latSeconds / 3600; latSeconds = Math.abs(latSeconds % 3600); int latMinutes = latSeconds / 60; latSeconds %= 60; int longSeconds = (int) Math.round(longitude * 3600); int longDegrees = longSeconds / 3600; longSeconds = Math.abs(longSeconds % 3600); int longMinutes = longSeconds / 60; longSeconds %= 60; String latDegree = latDegrees >= 0 ? "N" : "S"; String lonDegrees = longDegrees >= 0 ? "E" : "W"; return Math.abs(latDegrees) + "°" + latMinutes + "'" + latSeconds + "\"" + latDegree +" "+ Math.abs(longDegrees) + "°" + longMinutes + "'" + longSeconds + "\"" + lonDegrees; } catch (Exception e) { return ""+ String.format("%8.5f", latitude) + " " + String.format("%8.5f", longitude) ; } } 

Answer 4

Also pay attention to the Location class documentation, especially the convert() method, since it should do exactly what you want.

Answer 5

Abi's answer works very well in my location, but causes errors in some others, for example. "E" instead of "W" in the Western Hemisphere. IMO this should be:

 String lonDegrees = longDegrees >= 0 ? "E" : "W"; 

instead:

 String lonDegrees = latDegrees >= 0 ? "E" : "W"; 

Answer 6

Another way you can achieve this is to use the following function

 private String convertCoordinate(double coordinate, boolean isLatitude){ String[] pString = isLatitude ? new String[]{"N", "S"} : new String[]{"E", "W"}; int degree = (int) coordinate; int minute = (int) (Math.abs(coordinate) * 60) % 60; int second = (int) (Math.abs(coordinate) * 3600) % 60; int index = degree < 0 ? 1 : 0; degree = Math.abs(degree); return degree + pString[index] + " " + minute + "' " + second + "\""; } 

Answer 7

Based on SO answers, I made code that converts DEG to DMS using FORMAT

example: 40 ° 42'51 "N 74 ° 00'21" W

Call example: getLocationAsDMS (location, 8) 8 is the correct number for this format

 public String getLocationAsDMS (Location location, int decimalPlace){ String strLatitude = Location.convert(location.getLatitude(), Location.FORMAT_SECONDS); strLatitude = replaceDelimiters(strLatitude, decimalPlace); char latCardinal = location.getLongitude() >= 0 ? 'N' : 'S'; strLatitude = strLatitude + " " + latCardinal; String strLongitude = Location.convert(location.getLongitude(), Location.FORMAT_SECONDS); strLongitude = replaceDelimiters(strLongitude, decimalPlace); char lonCardinal = location.getLongitude() >= 0 ? 'E' : 'W'; strLongitude = strLongitude + " " + lonCardinal; return strLatitude + " " + strLongitude; } @NonNull private String replaceDelimiters(String str, int decimalPlace) { str = str.replaceFirst(":", "°"); str = str.replaceFirst(":", "'"); int pointIndex = str.indexOf("."); int endIndex = pointIndex + 1 + decimalPlace; if(endIndex < str.length()) { str = str.substring(0, endIndex); } str = str + "\""; return str; }
