Geodetic CRS: DVR90 height
Datum: Dansk Vertikal Reference 1990 ensemble
Data source: EPSG
Information source: Geodesy Division, Danish Agency for Climate Data (KDS); https://www.klimadatastyrelsen.dk/
Revision date: 2025-05-20
Scope: Change of height to a different vertical reference surface.
Remarks: Determined at 106 points, SD 0.006m. Offset: mean 0.005m, minimum -0.010m, maximum 0.017m. The transformation was derived using the levelling based DVR90(2000) (CRS code 10482), but is applicable to all realizations in the DVR90 ensemble.
Method: Vertical Offset by Grid Interpolation (gtg)
Area of use: Denmark - onshore Jutland, Funen, Zealand and Lolland.
