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