GeoCoordinateConverter

Convert between different representations of WGS-84 based geographic coordinates

Supported representations:

• Latitude/Longitude
• UTM
• MGRS

##iOS (Objective-C)

How to include it?

Copy the GeoCoordinateConverter folder into your project and drag the files right into your application.

How to you use it?

You use the functionality through the GeoCoordinateConverter class which provides four conversion methods:

- (void) utm:(NSString*) UTM ToLatitude:(double*) outLatitude Longitude:(double *) outLongitude;
- (NSString *) utmFromLatitude:(double) latitude Longitude:(double) longitude;
- (void) mgrs:(NSString*) MGRS ToLatitude:(double*) outLatitude Longitude:(double *) outLongitude;
- (NSString *) mgrsFromLatitude:(double) latitude Longitude:(double) longitude;

e.g.:

double latitude = 51.507351; 
double longitude = -0.127758;

GeoCoordinateConverter *converter = [GeoCoordinateConverter sharedConverter];
NSString *utm = [converter utmFromLatitude:latitude Longitude:longitude];

UTM coordinate strings are expected to be in this format:
<zone><latitude band> <easting> <northing> (e.g.: 30U 699319 5710158)

MGRS coordinate strings are expected to be in this format:
<zone><latitude band> <easting> <northing> (e.g.: 30UXC 99319 10158)

##Android (Java)

How to include it?

If you’re using the Eclipse Development Environment with the ADT plugin version 0.9.7 or greater you can include GeoCoordinateConverter as a library project.

Create a new Android project in Eclipse using the GeoCoordinateConverterLibrary folder as the existing source. Then, in your project properties, add the created project under the ‘Libraries’ section of the ‘Android’ category.

How to you use it?

You use the functionality through the GeoCoordinateConverter class which provides four conversion methods:

public double[] utm2LatLon(String UTM)
public String latLon2UTM(double latitude, double longitude)
public String latLon2MGRS(double latitude, double longitude)
public double[] mgrs2LatLon(String MGRS)

e.g.:

double latitude = 51.507351; 
double longitude = -0.127758;

GeoCoordinateConverter converter = GeoCoordinateConverter.getInstance( );
String utm = converter.latLon2UTM( city.latitude, city.longitude );

UTM coordinate strings are expected to be in this format:
<zone><latitude band> <easting> <northing> (e.g.: 30U 699319 5710158)

MGRS coordinate strings are expected to be in this format:
<zone><latitude band> <easting> <northing> (e.g.: 30UXC 99319 10158)
