Summary
Professional understanding of official geodetic spatial reference in Germany has evolved consistently over the past decade. In particular the AdV project »Repeated measurements in the German main height network (DHHN)« has contributed to a new approach. Today we speak of the »integrated geodetic spatial reference« as holistic approach of the geometrically and physically defined components. AdV working group »spatial reference« has placed this approach in the center of its new policy for the geodetic spatial reference of official surveying in Germany. In addition, special attention is dedicated to the quality assurance of the reference framework, which is realized by the unified field of geodetic control points.
