Vincenty's Direct
Given a geographic coordinate, an ellipsoidal distance, and a geodetic azimuth, use Vincenty's direct formula
to calculate the coordinate of a second point as well as the reverse geodetic azimuth. If the coordinate is
given using the Universal Transverse Mercator (UTM) coordinate reference system replace the geodetic azimuth
with a grid bearing and the ellipsoidal distance with a plane distance.
Notes:
- Latitude must be between 0° and ± 90°, and south latitudes are negative (e.g., -35° 55' 56.12"'); and
- Longitude must be between 0° and ± 180°, and west longitudes are negative (e.g., -148° 56' 25.12"').
- Calculations using UTM should only be done in the same or adjacent zones and in the same hemisphere. For
more widely separated points, geographic notation should be used.
Map Grid of Australia 2020 (MGA2020) is a UTM projection. The GRS80 ellipsoid must be selected to use
MGA2020, and calculations are only valid within the Geodetic Datum of Australia 2020 extent.
