GNTRANS2016 height

Attributes

Unit: metre

Geodetic CRS: GNTRANS2016 height

Datum: GNTRANS2016

Data source: EPSG

Information source: Deutsche Bahn AG via Geo++, www.geopp.de

Revision date: 2021-12-30

Scope: Engineering survey and topographic mapping for railway applications.

Remarks: Replaces GNTRANS height [also called GNTRANS2003 height] (CRS code 9923). Approximates national DHHN2016 height system (CRS code 7837) to around 1cm in lowlands and 2cm in high mountains.

Area of use: Germany - onshore - states of Baden-Wurtemberg, Bayern, Berlin, Brandenburg, Bremen, Hamburg, Hessen, Mecklenburg-Vorpommern, Niedersachsen, Nordrhein-Westfalen, Rheinland-Pfalz, Saarland, Sachsen, Sachsen-Anhalt, Schleswig-Holstein, Thuringen.

Coordinate system: Vertical CS. Axis: height (H). Orientation: up. UoM: m.
