Any several geodetic datum utilizations in implementation of mapping in Indonesia result in spatial data integration problem. By the reason, Bakosurtanal was implements Datum Geodetik Nasional 1995 (DGN-95) as single datum for mapping in Indonesia. The transformation parameter availability of preceding datum to DGN-95 needed in spatial data integration process. This paper stems from research of transformation model use of Molodensky-Badekas in measure of transformation parameter of Datum Bessel 1841 to DGN-95 in the North Sumatra. By result, it is shows that datum parameter values are ΔX = -376,900 m, ΔY = 681,024 m, and ΔZ = -50,102 m. There are any differences about dΔX = 0,100 m, dΔY = 0,024 m, and dΔZ = -0,102 m on publicized parameter scores of U.S. NIMA as the comparison data..
