QLD_PNDB_ID	Yes	Long		Queensland Place Names Database unique identifier
ATTRIBUTE_SOURCE	No	Text	100	If the feature is named, the attribute_source is the source imagery, map, or data from which the features name has been obtained. If the feature is not named, the attribute_source is the source imagery, map, or data used to define what the feature type is.
ATTRIBUTE_DATE	No	Date		Date of the source imagery, map, or data used for attributing the feature.
ADDITIONAL_NAMES	Yes	Test	100	Other names of the feature if not recorded in the Queensland Place Names Database. May be commonly known by other names or have different spelling. Multiple names can be shown, separated by a comma.
ADD_NAMES_SOURCE	Yes	Text	100	The source map or data that the additional names were obtained. Multiple sources can be shown, separated by a comma. If multiple sources are shown, the written sequence will be the same as the written sequence of the names themselves.
FEATURE_SOURCE	No	Text	100	The source imagery, map, or data that the spatial location of the feature was obtained from.
FEATURE_DATE	No	Date		Date of the source imagery, map, or data that the spatial location of the feature was obtained from.
ELEVATION_M	Yes	Double		The elevation of the feature measured in metres in relation to the Australian Height Datum. This field only relates to Capes, Mountains and Passes otherwise left blank

PFI	No	Text		A Persistent Feature Identifier (PFI) is generated for each feature at the point of creation in the database. The value of the PFI will stay with the feature through all changes to the feature (both spatial and non-spatial) until the feature is retired. (See Persistent and Unique Feature Identifiers)
UFI	No	Text		A Unique Feature Identifier (UFI) is generated for each new feature at the point of creation in the database (at this point the PFI and UFI will be the same). The value of the UFI will stay with the feature through all changes to the feature (both spatial and non-spatial) unless the feature is split into multiple other parts. If the feature is split, the separate parts will retain the original PFI but new UFI’s will be generated for the split parts. (See Persistent and Unique Feature Identifiers)

TEXT_NOTE	Yes	Text	50	For mapping purposes. Additional annotation that can be shown on a map. If the feature type is classified as mountain, transfer the elevation and unit of measurement (typed in lower case) into this field. e.g., 150m
ADD_INFORMATION	Yes	Text	255	A comment field (additional information)
