- Geodætisk Institut
Geodætisk Institut (1928-1987) was a Danish state-run
cartographic institute.It was created by law number 82, of
March 31 ,1928 , combiningGeneralstabens Topografiske Afdeling andDen danske Gradmaaling , two institutions that did somewhat overlapping cartographic andtopographic 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 withMatrikeldirektoratet andSøkortarkivet , to formKort & Matrikelstyrelsen .Geodætisk Institut departments
