    Description copied from interface: UncertaintyGenerator
    
    Generates the combined uncertainty for a given band maths expression.
    
    Specified by:
    
    generateUncertainty in interface UncertaintyGenerator
    
    Parameters:
    
    product - The data product that serves the referenced rasters in the expression.
    
    relation - Relation name of ancillary variables that represent uncertainties (NetCDF-U 'rel' attribute).
    
    expression - The band maths expression.
    
    Returns:
    
    A new band maths expression representing the combined uncertainty.
    
    Throws:
    
    ParseException
    
    UnsupportedOperationException
