Official EPSG transformation from RGTAAF07 to WGS 84

The EPSG Geodetic Parameter Dataset defines 1 transformation between RGTAAF07 (EPSG:7073) and WGS 84 (EPSG:4326). Its parameters, accuracy and area of use are listed below.

RGTAAF07 to WGS 84 (1)

EPSG:9770±1 m

Method:: Geocentric translations (geog2D domain)
Area of use:: French Southern and Antarctic Territories
Scope:: (null/copy) Approximation for medium and low accuracy applications assuming equality between plate-fixed static and earth-fixed dynamic CRSs, ignoring static/dynamic CRS differences.

Parameter	Value	Unit
X-axis translation(tx)	0	metre
Y-axis translation(ty)	0	metre
Z-axis translation(tz)	0	metre

For many purposes RGTAAF07 can be considered to be coincident with WGS 84. This approximation ignores the low accuracy of the WGS 84 ensemble and the application of tectonic plate motion to WGS 84 data.

Frequently asked questions

How accurate is converting RGTAAF07 to WGS 84?: The most accurate official EPSG transformation between these systems is accurate to about ±1 m within its stated area of use. Browser-based converters approximate datum shifts with Helmert parameters; for surveying-grade work apply the official transformation in a desktop GIS.
Does my data leave the browser when I use this converter?: No. All coordinate transformations are computed locally in your browser using proj4js. The coordinates you enter are never transmitted to any server.
