Official EPSG transformation from LKS-92 to LKS-2020

The EPSG Geodetic Parameter Dataset defines 1 transformation between LKS-92 (EPSG:4661) and LKS-2020 (EPSG:10305). Its parameters, accuracy and area of use are listed below.

LKS-92 to LKS-2020 (1)

EPSG:10838±0.02 m
Method:
NTv2
Area of use:
Latvia
Scope:
Spatial referencing.

Grid file: LKS92to2020NTv2.gsb

Accuracy of transformation is at 1 cm level one sigma. Care! The NTv2 format requires longitudes to be positive west. At a given point, LKS-2020 latitude (positive north) has a greater value than LKS-92 latitude and LKS-2020 longitude (positive east) has a lesser value than LKS-92 longitude. For point Odukalns: 56.8283960°N, 24.2727688°E (LKS-92) = 56.8283967°N, 24.2727679°E (LKS-2020).

Frequently asked questions

How accurate is converting LKS-92 to LKS-2020?
The most accurate official EPSG transformation between these systems is accurate to about ±0.02 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.
