About converting QazTRF-23 to WGS 84

QazTRF-23 (EPSG:10941) is Kazakhstan's geodetic reference frame adopted in 2023 — an ITRF2020 realisation that replaces the Soviet SK-42/SK-95 lineage for official Kazakh geodesy.

Against WGS 84 it is a metre-level null transformation, like other modern ITRF-aligned national frames. Its real significance is as the migration target for Kazakhstan's huge SK-42 archives: mining, oil and gas, and cadastral data accumulated over seven decades.

Expect Kazakh official products to reference QazTRF-23 and its projected zones going forward, with Pulkovo-based Gauss–Krüger zones living on in legacy material.

Official EPSG transformation from QazTRF-23 to WGS 84

The EPSG Geodetic Parameter Dataset defines 1 transformation between QazTRF-23 (EPSG:10941) and WGS 84 (EPSG:4326). Its parameters, accuracy and area of use are listed below.

QazTRF-23 to WGS 84 (1)

EPSG:10965±1 m

Method:: Geocentric translations (geog2D domain)
Area of use:: Kazakhstan
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 that QazTRF-23 is equivalent to WGS 84 within the accuracy of the transformation.

Frequently asked questions

How does QazTRF-23 relate to WGS 84?: They agree at the metre level — QazTRF-23 is an ITRF2020 realisation. The published EPSG operation is a ±1 m null transformation.
What happens to SK-42 data in Kazakhstan?: It remains valid as legacy material; the published Pulkovo 1942 transformations (fitted for Kazakhstan) bridge it to modern frames, typically via QazTRF-23 for official work.
How accurate is converting QazTRF-23 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.
