Geodætisk Institut
Geodætisk Institut (1928-1987) was a
Danish state-run
cartographic institute.
It was created by law number 82, of
March 31,
1928, combining
Generalstabens Topografiske Afdeling and
Den danske Gradmaaling, two institutions that did somewhat overlapping cartographic and
topographic mapping of Denmark. It was initially part of
Ministry of War (Krigsministeret), later
Ministry of Defence (Forsvarsministeret).
In the years
1940-
1953 Geodætisk Institut made the second nation-wide precision landscape levelling of Denmark. The first was done
1885-
1905 by
Den danske Gradmaaling. The height fix point remains
Århus Domkirke (
Dansk Normal Nul (DNN)), as established in
1905.
A third levelling was done
1982-
1994. This formed the basic for the new height system
DVR90, replacing DNN. The height fix point remains Aarhus Domkirke, however its kote was changed from 5.6150m to 5.570m in DVR90.
Geodætisk Institut made the third topographic mapping of Denmark in the years
1966-
1987, based on
aerial photography. (First 1842-1887, second 1887-1938)
Starting in
1953 Geodætisk Institut made a whole set of new maps 1:25,000, 1:50,000 and 1:100.000, all based on
UTM/
ED50 map projections, where Denmark is located in zone 32 and 33. This work was finished in
1975.
By royal resolution of
September 10,
1987,
Geodætisk Institut was combined with
Matrikeldirektoratet and
Søkortarkivet, to form
Kort & Matrikelstyrelsen.
