EPSG:5711

AHD height

Attributes

Unit: metre

Geodetic CRS: AHD height

Datum: Australian Height Datum

Data source: EPSG

Information source: GDA2020 Technical Manual v1.4 and Australian Vertical Working Surface (AVWS) Technical Implementation Plan v1.2 (http://www.icsm.gov.au).

Revision date: 2020-10-21

Scope: Cadastre, engineering surveying applications over distances up to 10km.

Remarks: Appropriate for cadastral and local engineering survey including construction or mining. Only suitable onshore. AVWS height (CRS code 9458) is more accurate than AHD height for applications over distances greater than 10 km and also extends offshore.

Area of use: Australia - Australian Capital Territory, New South Wales, Northern Territory, Queensland, South Australia, Tasmania, Western Australia and Victoria - onshore. Christmas Island - onshore. Cocos and Keeling Islands - onshore.

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