Lat = 52°27'12.021" N,
Lon = 13°22'04.928" E
Datum realization epoch1990
Datum valid area
Germany, used in Federal State Thüringen
Datum scope
Datum remarks
- created by 4 parameter ellipsoidial transformation of 
coord. of Datum 42/83, parameters are computed with 13 
identical points between Datum DHDN represent by points of 
old  Reichsdreiecksnetz RDN and Datum 42/83 along the 
former border between Germany East and West  
- central point of former network Reichsdreiecksnetz, 
which was the basis of DHDN / PD/83 / RD/83 was Rauenberg 
in Berlin, this point was destroyed in 1910 and substitute 
by point Potsdam, therefore the aliases Rauenberg Datum and 
Potsdam Datum are known for German Datums  
- the abbreviation PD/83 means Potsdam Datum/83 to have a 
distinction to RD/83 and is the concrete realisation of 
DHDN in Federal State Thüringen
