NavigatedCoordinateSystem

public NavigatedCoordinateSystem(RealTupleType reference,
                                 Unit[] units)
                          throws VisADException

Constructs from the type of the reference coordinate system and units for values in this coordinate system. The reference coordinate system must contain RealType.Latitude and RealType.Longitude.

Parameters:

reference - The type of the reference coordinate system. The reference must contain RealType.Latitude and RealType.Longitude. Values in the reference coordinate system shall be in units of reference.getDefaultUnits() unless specified otherwise.

units - The default units for this coordinate system. Numeric values in this coordinate system shall be in units of units unless specified otherwise. May be null or an array of null-s.

Throws:

VisADException - Couldn't create necessary VisAD object or reference does not contain RealType.Latitude or RealType.Longitude.
