EPSG:10256

GS-IRF

Attributes

Unit: degree (supplier to define representation)

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: Intermediate stage in transformations - not used otherwise.

Remarks: Artificial CRS created in 2022 to assist the transformation of coordinates between the historic Generalstabens System and ETRS89 through CT ETRS89 to GS-IRF (1) (code 10259) used in conjunction with the GS LCC map projection (code 10257).

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

Coordinate system: Ellipsoidal 2D CS. Axes: latitude, longitude. Orientations: north, east. UoM: degree
