Engineering survey.
For large scale topographic mapping and cadastral survey ETRS89 / Kp2000 Jutland (CRS code 2196) is used. For medium and small scale topographic mapping ETRS89 / UTM zone 32N (CRS code 25832) is used.
Denmark - onshore - Jutland east of 9°E and Funen.
Cartesian 2D CS. Axes: easting, northing (E,N). Orientations: east, north. UoM: m.
