In 2005 the first update of the DFHRS for Baden-Württemberg for NN-heights was computed. The update became
necessary with the introduction of the new co-ordinates of the SAPOS reference stations in 2003. The
1cm DFHRS DB for the NHN92 Normal Height system has also been completed. It can - with respect to the
introduction of the new German/European Normal Height system NHN92 as official HRS for Baden-Württemberg,
starting at 1-January-2008 - be ordered from now.
All DFHRS databases are related to the above ellipsoidal co-cordinates 2003 of the 130 BWRef-Points.
