Constructor Detail

TransverseMercator.Parameters

public TransverseMercator.Parameters(ParameterDescriptorGroup descriptor,
                                     ParameterValueGroup values)
                              throws ParameterNotFoundException

Creates parameters initialized to values extracted from the given parameter group.

Parameters:

descriptor - The descriptor of parameters that are legal for the projection being constructed.

values - The parameter values in standard units.

Throws:

ParameterNotFoundException - if a mandatory parameter is missing.

Method Detail

getZone

public int getZone()
            throws IllegalStateException

Convenience method computing the zone code from the central meridian. This method uses the scale factor and false easting to decide if this is a UTM or MTM case.

Returns:

The zone number. Numbering starts at 1.

Throws:

IllegalStateException - if the case of the projection cannot be determined.

getCentralMeridian

public double getCentralMeridian()
                          throws IllegalStateException

Convenience method returning the meridian in the middle of current zone. This meridian is typically the central meridian. This method may be invoked to make sure that the central meridian is correctly set.

This method uses the scale factor and false easting to decide if this is a UTM or MTM case.

Returns:

The central meridian, in decimal degrees.

Throws:

IllegalStateException - if the case of the projection cannot be determined.
