There's an example of doing this in the getLongitudes() method
of visad/ But note this isn't for the
most general case, which may include a CoordinateSystem on the
data side (it does show how to deal with a CoordinateSystem on
the display side, and how to deal with ScalarMap scaling). But
usually (lat, lon) are the reference of a data side
CoordinateSystem, in which case it isn't necessary to deal
with the data side CoordinateSystem.
