Official EPSG transformation from EST97 to WGS 84

The EPSG Geodetic Parameter Dataset defines 1 transformation between EST97 (EPSG:4180) and WGS 84 (EPSG:4326). Its parameters, accuracy and area of use are listed below.

EST97 to WGS 84 (1)

EPSG:1649±1 m

Method:: Geocentric translations (geog2D domain)
Area of use:: Estonia
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

Approximation at the +/- 1m level assuming ETRS89 and WGS 84 can be considered the same to within the accuracy of the transformation. EST97 is a national densification of ETRS89.

Frequently asked questions

How accurate is converting EST97 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.
