Specifying Level Information in an Address

If you use the G-NAF database the geocoder can return level information for some addresses. Level information identifies the floor or level of a multi-storey building. The G-NAF database includes level information for some Australian states. Level information may be associated with unit information, but not necessarily. If the G-NAF database contains multiple records with the same level, the level information is returned only if the input address contains unique content (such as a unit number).

If the G-NAF database has level information for an address, the geocoder returns that information with the matched candidate. The correct level information is returned (when available) even if the input address did not include level information, or if the input had the wrong level information.

If the input address has level information but the G-NAF database does not include level information for the matching address, then the input level information is discarded since it is not validated in the G-NAF data.

Following are several examples of partial addresses that contain level information. The level information is indicated in bold.
