Method Detail

convertGeodeticToUPS

public long convertGeodeticToUPS(double latitude,
                                 double longitude)

The function convertGeodeticToUPS converts geodetic (latitude and longitude) coordinates to UPS (hemisphere, easting, and northing) coordinates, according to the current ellipsoid parameters. If any errors occur, the error code(s) are returned by the function, otherwide UPS_NO_ERROR is returned.

Parameters:

latitude - latitude in radians

longitude - longitude in radians

Returns:

error code

getEasting

public double getEasting()

Returns:

easting/X in meters

getNorthing

public double getNorthing()

Returns:

northing/Y in meters

getHemisphere

public Hemisphere getHemisphere()

Returns:

hemisphere, either Hemisphere.N of Hemisphere.S.

convertUPSToGeodetic

public long convertUPSToGeodetic(Hemisphere hemisphere,
                                 double easting,
                                 double northing)

The function Convert_UPS_To_Geodetic converts UPS (hemisphere, easting, and northing) coordinates to geodetic (latitude and longitude) coordinates according to the current ellipsoid parameters. If any errors occur, the error code(s) are returned by the function, otherwise UPS_NO_ERROR is returned.

Parameters:

hemisphere - hemisphere, either Hemisphere.N of Hemisphere.S.

easting - easting/X in meters

northing - northing/Y in meters

Returns:

error code

getLatitude

public double getLatitude()

Returns:

latitude in radians.

getLongitude

public double getLongitude()

Returns:

longitude in radians.
