On the first pass through, you create a bunch of RealTypes.
On the second pass, you're again trying to create them.
VisAD only allows a given type to be created once.
Instead of doing:
latitude = new RealType("latitude");
longitude = new RealType("longitude");
domain_tuple = new RealTupleType(latitude, longitude);
altitude = new RealType("altitude", SI.meter, null);
you should do:
latitude = RealType.getRealType("latitude");
longitude = RealType.getRealType("longitude");
domain_tuple = RealType.getRealTupleType(latitude, longitude);
altitude = RealType.getRealType("altitude", SI.meter, null);
