Geodetic Reference Systems — Heavy Duty Points

The Deutsche Hauptschwerenetz (DHSN) contributes to the realisation of the height reference system throughout Germany and manages the official severity values. The SFPs are definitions that are physically determined, geodetically secured and measured. Their data is recorded under a point mark in the proofs of the fixed points. The proofs of the fixed points are divided into an overview of the fixed points based on the topographic map 1:25,000 (TK25) as a point signature with point number, a point description (measurement sketch) and a point file (heavy value).
