Function hierarchy

The population of Primary Function and Secondary Function attributes is driven by a hierarchy. This hierarchy is applied to the data to determine which function is primary and secondary in cases where more than one function applies for a single topographic area polygon. Not every polygon will have more than one function due to the nature of the primary function, for example, cemeteries and bowling greens are not likely to have secondary functions. This hierarchy only applies where more than one function exists.

The hierarchy has been developed to ensure the process applies the appropriate functions and does not imply any level of priority.

The following table declares this hierarchy:

*Due to the way Amenity – Residential or Business function is defined (see Code lists), features classified as this primary function would not be expected to have a secondary function.
