Official EPSG transformations from HD72 to ETRF2000

The EPSG Geodetic Parameter Dataset defines 2 transformations between HD72 (EPSG:4237) and ETRF2000 (EPSG:9067). Each applies to a specific area — pick the one whose area of use covers your data.

HD72 to ETRF2000 (1)

EPSG:10663±0.01 mBest accuracy
Method:
NTv2
Area of use:
Hungary
Scope:
Geodesy, cadastre, engineering survey, topographic mapping.

Grid file: hu_sgo_hd72corr.gsb

Used in the official SGO EHT coordinate transformation tool. For access to the grid file see https://www.gnssnet.hu/.

HD72 to ETRF2000 (2)

EPSG:10668±0.015 m
Method:
NTv2
Area of use:
Hungary
Scope:
Geodesy, engineering survey, topographic mapping.

Grid file: hu_bme_hd72corr.gsb

Emulation to better than 2mm of the official SGO EHT transformation. ETRF2000 coordinates of the grid nodes were converted to HD72 using the online EHT tool. For cadastral and other legal purposes the official transformation (CT code 10663) must be used.

Frequently asked questions

How accurate is converting HD72 to ETRF2000?
The most accurate official EPSG transformation between these systems is accurate to about ±0.01 m within its stated area of use. Browser-based converters approximate datum shifts with Helmert parameters; for surveying-grade work apply the official transformation (including the grid-shift files listed below) 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.
