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

15

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)

CREATED_DATE*

No

Date

The date the feature was originally captured and first loaded to the database

*Internal use only

LAST_EDITED_DATE*

No

Date

Date of the last editing or revision to the feature

*Internal use only

DIMENSION_M

No

Double

The length of the feature measured in metres GDA2020

UPPER_SCALE

No

Long

The upper scale for which the feature should be considered suitable for digital display

COASTLINE

Definition: - The line defining boundary between the mainland, marine (offshore) islands, and the sea being Mean High Water (MHW).

Alternate Terms: Coast, State border

·       Capture as a 2D polyline.

·       The location is plotted from orthorectified imagery

·       Feature Type “Coastline” Foundation - “Coastline” is positioned at Mean High Water (MHW).

·       The other two “Coastline” Formation features are Indefinite Coastline and Rocky Foreshore.

“Indefinite Coastline” is captured coincident with the seaward edge of any vegetation (mangrove) below Mean High Water (MHW)

“Rocky Foreshore” is captured at Mean High Water (MHW) observed on the rocky coastal foreshore. (natural or constructed)

·       The Feature Type “Coastline” does not cross the entrances of identified waterbody areas features (greater than 30 metres) meeting the sea. This is when a “Coastline Junction” feature is placed.

COASTLINE JUNCTION

Definition: - The artificial line between waterbodies of the mainland, marine (offshore) islands and the sea.

Alternate Terms:

·       Capture as a straight 2D polyline

·       The polyline is the placed as the connector cross the entrances of identified waterbody areas meeting the Sea, joining the two sides of the Feature Type “Coastline”.

·       The polyline has a vertex placed midway to snap the waterbody area connector.

·       Always show “Formation” – Not Applicable
