MappingDialog extracts the ScalarTypes using visad.util.DataUtility's
getScalarTypes() method (this method calls several other internal, recursive
methods to which I alluded before). Check out the Javadoc on
visad.util.DataUtility for more information on its usage.

You should be able to getData() your data from the SSCell, then call
DataUtility.getScalarTypes, passing in your data objects.
