AVWS height

Attributes

Unit: metre

Geodetic CRS: AVWS height

Datum: Australian Vertical Working Surface

Data source: EPSG

Information source: Australian Vertical Working Surface (AVWS) Technical Implementation Plan v1.2, 26th August 2020, ANZLIC Intergovernmental Committee on Surveying and Mapping (ICSM) (http://www.icsm.gov.au).

Revision date: 2021-12-03

Scope: Geodesy, hydrography, transfer of accurate heights over distances greater than 10km.

Remarks: For cadastral and local engineering applications see AHD height (CRS code 5711). AVWS is more accurate than AHD for applications over distances greater than 10 km.

Area of use: Australia including Lord Howe Island, Macquarie Island, Ashmore and Cartier Islands, Christmas Island, Cocos (Keeling) Islands, Norfolk Island. All onshore and offshore.

Coordinate system: Vertical CS. Axis: height (H). Orientation: up. UoM: m.

Center coordinates
-34.51 133.38

Projected bounds:
-60.55 93.41
-8.47 173.34

WGS84 bounds:
93.41 -60.55
173.34 -8.47
