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

convertUPSToGeodetic

public long convertUPSToGeodetic(char 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 'N' or 'S'; Easting - Easting/X in meters; Northing - Northing/Y in meters
Returns:: error code

getEasting

public double getEasting()

Returns:: Easting/X in meters

getHemisphere

public char getHemisphere()

Returns:: Hemisphere 'N' or 'S'

getLatitude

public double getLatitude()

Returns:: Latitude in radians.

getLongitude

public double getLongitude()

Returns:: Longitude in radians.

getNorthing

public double getNorthing()

Returns:: Northing/Y in meters

setUPSParameters

public long setUPSParameters(double a,
                             double f)

The function SetUPSParameters receives the ellipsoid parameters and sets the corresponding state variables. If any errors occur, the error code(s) are returned by the function, otherwise UPS_NO_ERROR is returned.

Parameters:: a - Semi-major axis of ellipsoid in meters; f - Flattening of ellipsoid
Returns:: error code
