The first official national Australian geodetic datum was actually called the Australian Geodetic Datum (AGD). It was proclaimed in the Australian Commonwealth Gazette No. 84 of 6 October 1966.

2001年2月7日 · EPSG:4203 Geodetic coordinate system for Australia - Queensland, South Australia, Western Australia, federal areas offshore west of 129°E. National system replacing AGD66 but officially adopted only in Queensland, South Australia and Western Australia. Replaced by GDA94. Geodesy.

2021年3月31日 · The MGA Zone 55 projection of GDA94 geographic coordinate system transposes it to a flat surface. Note the removal of the globe/curve, change from degrees to metres, and distortion to the west and east.

Area of use: Australia - onshore and offshore between 144°E and 150°E. Papua New Guinea (PNG) - onshore between 144°E and 150°E. Coordinate system: Cartesian 2D CS. Axes: easting, northing (E,N). Orientations: east, north. UoM: m. EPSG:20255 Projected coordinate system for Australia - onshore and offshore between 144°E and 150°E.

2020年4月8日 · Both projections are divided into eight equal zones across Australia. Sydney, for example, falls with MGA zone 56. Depending on the coordinate system adopted, Sydney, for example, could be classified as either GDA94 / MGA zone 56 (EPSG: 28356) or GDA2020 / MGA zone 56 (EPSG: 7856).

eplacing the Australian Geodetic Datum (AGD). GDA is part of a Global Geodetic Reference Frame (GGRF) and is directly compatible with Global Navigation Satellite Systems (GNSS) …

GDA94 is a coordinate reference system whose origin coincides with a determination of the centre of mass of the earth, hence the term ‘geocentric’. GDA94 is a ‘plate-fixed’ or ‘static’ coordinate datum based on the International Terrestrial Reference Frame 1992 (ITRF92), held at the reference epoch of 1 January 1994.

The AGD and GDA are two different mathematical models of the shape of the Earth. Each has a different origin and subsequently a point on the Earth’s surface will have different coordinates based on each datum. While features on the ground …

This utility transforms coordinates between AGD66 and GDA94 using the Regional NSW/Victorian seven parameter set. Select your coordinate type, enter your geographic or grid coordinates, then click on the Transform button. A separate window will display the transformation results for all coordinate types.

MGA Zones for NSW. GDA Lambert Projection for NSW (GDA94 Lambert, GDA2020 Lambert) This Lambert projection is suitable for state-wide GIS data in NSW. To ensure uniformity across agencies, the Surveyor General has endorsed the following parameters for …
