Location and height of the connection points in the area of the city area Aachen.
As of 1 December 2016, the Länder of the Federal Republic of Germany introduced a new realisation of the official geodetic spatial reference, the so-called integrated spatial reference 2016. This now provides uniform and highly accurate coordinates for location and height as well as severity values.
In this context, the location coordinates and the height values have been adjusted after the most recent survey data have been evaluated. While no significant changes were made for the location coordinates, the height values in Aachen have changed from + 1.5 cm to + 2.0 cm. The new designation of the heights is “heights above normal height zero (NHN) in DHHN2016”.
