Capture Process:

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

Pondage Areas

Feature Type definitions:

Pondage Area – Body of water used in aquaculture, the treatment of water and/or other industrial uses. They are not a part of the drainage network.

Function definitions:

Aquaculture Area – Shallow beds, usually segmented by constructed walls or leased areas within natural waterways used for the commercial breeding and keeping of aquatic animals or plants.

Salt Evaporator - A flat shallow area, used for the commercial production of salt by evaporation.

Settling Pond-Shallow Pond, usually segmented by constructed walls, used for the treatment of sewage or other wastes or as water storage areas by various organisations.

Upper scale:

Individual features may not agree with the following specifications to improve mapping legibility.

1:25 000 – < 22,500 m²

1:100 000 – >/= 22,500 m² and < 140,625 m²

1:250 000 – >/= 140,625 m² and < 1,000,000 m²

1:1 000 000 – >/= 1,000,000 m² and < 10,000,000 m²

1:2 500 000 – >/= 10,000,000 m² and < 34,000,000 m²
