VisAD does maintain a static Vector of ScalarTypes.  To reuse the same
ScalarType again, use the following code:

RealType xRT = (RealType) ScalarType.getScalarTypeByName("latitude");
if (xRT == null) xRT = new RealType("latitude", null, null);

This code searches the static Vector for an already existing RealType
called latitude.  If it can't find it, it creates it.
