4 Official reference systems and frames... In 2000 requested 3 expert studies from GEOF UNIZG: for horizontal and gravimetric datum (prof. dr. sc. Tomislav Bašić), HTRS96 for height datum (late prof. dr. sc. Ladislav Feil) & for cartographic projections (prof. dr. sc. Miljenko Lapaine) In 2001 studies were reviewed by foreign experts: E. Brockmann, B. - G. Harsson, J. Ihde On 4 th August 2004 Croatian Government Decree on establishing new official geodetic datums and map projections of the Republic of Croatia Croatian Terrestrial Reference System 1996 (HTRS96) ETRS89; GRS80 system 78 permanently stabilized points (ITRF96, e ETRS89) frame
