  • Latvia - onshore and offshore. , accuracy 0.02 m, code 10838 (default) [grid]

Selected transformation

Name: LKS-92 to LKS-2020 (1)

Method: NTv2

Grid Files: LKS92to2020NTv2.gsb

Remarks: 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).
