Field Name | Description |
---|---|
GNAF_ADDRESS_CLASS | The Address_Class is constructed using a combination of elements
from the G-NAF Data Dictionary source tables. The components of the
Address_Class field are:
|
GNAF_CONFIDENCE | A number indicating how many G-NAF datasets the address is found in. A higher confidence level means that the same address was found in more data contributor sources. One of the following:
|
GNAF_EIGHT_DECIMAL_PLACE_LATITUDE | The parcel latitude, precise to eight digits after the decimal. This is the latitude that the candidate matched to in the G-NAF database. These are the original coordinates directly from the G-NAF data prior to truncation or rounding. This field is only returned if you check the Return eight decimal places for parcel latitude/longitude box on the Geocoding tab. |
GNAF_EIGHT_DECIMAL_PLACE_LONGITUDE | The parcel longitude, precise to eight digits after the decimal. This is the longitude that the candidate matched to in the G-NAF database. These are the original coordinates directly from the G-NAF data prior to truncation or rounding. This field is only returned if you check the Return eight decimal places for parcel latitude/longitude box on the Geocoding tab. |
GNAF_GEOCODE_LEVEL | A number indicating the level o f geocode for the address. Every principal address within the G-NAF database has at least a locality level geocode. They may also have a street level geocode and a point level geocode. One of the following:
|
GNAF_PARCEL_ID | The Parcel ID field is the generic parcel id field provided by custodial data, and represents a Lot on Plan description that is useful for government agencies. The exact format varies. G-NAF source data has over 7 million records with a Parcel_ID. The Australia geocoder supplements this to populate over 12,730,000 G-NAF records with a Parcel_ID field. |
GNAF_PID | The G-NAF Persistent Identifier (G-NAF PID) is a 14-character alphanumeric string that uniquely identifies each G-NAF address. The PID is constructed from a combination of the major address fields of the G-NAF database. An example of a G-NAF PID is: GAACT718519668 |
GNAF_RELIABILITY | A number indicating the geocode precision. Reliability is related to the dictionary used to determine the geocode. Data with geocoded reliability levels 1, 2, and 3 is contained in the GNAF123 Dictionary. This is point (parcel) level geocoded data. Data with geocoded reliability levels 4, 5, and 6 is contained in the GNAF456 Dictionary. This contains non-parcel centroid geocoded data.
|
GNAF_SA1 | The Statistical Area Level 1 (SA1) field as the second smallest geographic area defined in the Australian Statistical Geography Standard (ASGS). Mesh Block is the smallest unit. The SA1 is designed for use in the Census of Population and Housing as the smallest unit for the processing and release of Census data. An SA1 is represented by a unique seven digit code. |
LEVEL_NUMBER | The number of a floor or level in a multistory building. For example, Floor 2, 17 Jones Street 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, that information is returned 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. |
LEVEL_TYPE | The label used for a floor of a multistory building. For example, "Level" or "Floor". In this example, the level type is "Level": Suite 3 Level 7, 17 Jones Street In this example, Suite 3 is a unit. 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, that information is returned 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. |
MESH_BLOCK_ID | A Meshblock is the smallest geographic unit for which statistical data is collected by the Australian Bureau of Statistics (ABS). Meshblocks usually contain a minimum of 20 to 50 households. This is about one fifth the size of a Collection District (CD). You can use the Meshblock ID to do additional attributions against your own data. |
LOT_NUMBER | Lot numbers are returned for G-NAF candidates because some rural addresses do not have adequate physical or house number information. |
STREET_TYPE_ABB | This is an abbreviation for the street type. For example, EX is an abbreviation for Extension and FTRL is an abbreviation for Firetrail. |
