EPSG:10258

GS reconstruction east-orientated

Attributes

Unit: metre

Geodetic CRS: GS-IRF

Datum: Generalstabens System Intermediate Datum

Ellipsoid: Danish 1876

Prime meridian: Greenwich

Data source: EPSG

Information source: The Danish Agency for Data Supply and Infrastructure, https://sdfi.dk

Revision date: 2023-05-10

Scope: Topographic mapping.

Remarks: Reconstruction emulating the historic Generalstabens System CRS but with axis direction flip: W (GS) = E (GS e-o) * -1, N (GS) = N (GS e-o). Reconstructed through CT ETRS89 to GS-IRF (1) with map projection GS LCC (codes 10259 and 10257).

Area of use: Denmark - onshore Jutland, Funen, Zealand and Lolland.

Coordinate system: Cartesian 2D CS. Axes: easting, northing (E,N). Orientations: east, north. UoM: m.
