Method Detail

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

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 java.lang.String getHemisphere()

Returns:

Hemisphere, either AVKey.NORTH or AVKey.SOUTH.

convertUPSToGeodetic

public long convertUPSToGeodetic(java.lang.String 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 AVKey.NORTH or AVKey.SOUTH.

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.
