The source imagery, map, or data that the spatial location and shape of the of the feature was obtained from.

 

 

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)

titleCapture Process:

 

GULF

 

Definition: A named large inlet of the sea almost surrounded by land.

 

(The name of the sea and ocean that the gulf is within, is included in the Additional Names field).

 

Alternate Terms:

 ·        

  • Capture as a 2D polygon

·        

  • The actual extent of a Gulf is fuzzy and as such hard to define.

·        

  • Locate the extent from maritime charts, other datasets, existing mapping, organisations, Local Government websites, or other source material.

·        

  • Capture the boundary of the gulf coincident with the defined Coastline and Coastline Junctions. The polygon is completed by a straight line joining the approximate points where the recess into the land starts and finishes.

·        

  • The seaward extent of the Gulf of Carpentaria has been taken as a straight line from Cape Arnhem in the Northern Territory to Cape Slade on Cape York Peninsula.

  • Only named gulfs are captured.

 

 

SEA

 

Definition: A named large body of salt water that is surrounded in whole or in part by land.

 

(The name of the ocean that the sea is within, is included in the Additional Names field).

 

Alternate Terms: Ocean

 

 ·        

  • Capture as a 2D polygon

·        

  • Locate the extent from maritime charts, other datasets, existing mapping, organisations, Local Government websites, or other source material.

·        

  • Capture the boundary of the sea coincident with the defined Coastline and Coastline Junctions. The seaward extent of the ocean is to the edge of Australia’s Maritime Exclusive Economic Zone.

·        

  • Include the relevant ocean name in Additional names field. Source being

the International Hydrographic Organisation, Limits of Oceans and Seas 3rd edition Published 1953.·         The boundary between the Coral and Arafura Seas is that defined by

  • the International Hydrographic Organisation, Limits of Oceans and Seas 3rd edition Published 1953.

·           

  • The boundary between the Coral and Arafura Seas is that defined by the International Hydrographic Organisation, Limits of Oceans and Seas 3rd edition Published 1953.

  • Only named seas are captured.

 

 

STRAIT

 

Definition: A named large navigable waterway that connects two larger bodies of water.

 

(The name of the sea and ocean that the strait is within, is included in the Additional Names field).

 

Alternate Terms:

 

 ·        

  • Capture as a 2D polygon

·        

  • Locate the extent from maritime charts, other datasets, existing mapping, organisations, Local Government websites, or other source material.

·        

  • Capture the boundary of the strait coincident with the defined Coastline and Coastline Junctions. The seaward extent of the ocean is to the edge of Australia’s Maritime Exclusive Economic Zone.

·        

  • The boundary of the Torres Strait was obtained from the International Hydrographic Organisation, Limits of Oceans and Seas 4th edition Published 2002. This edition however has never been ratified.

·        

  • Note – Smaller straits such as the Great Sandy Strait, Endeavour Strait and Turkeys Strait are depicted in the “Linear Landforms” dataset.

  • Only named straits are captured.
