Contents of the geodetic archive

The Geodetic Archive contains records and measurement documents from the end of the 18th century onwards.

The extensive content of the geodetic archive comprises e.g. measurements and calculations for the national geodetic reference networks - GNSS measurements, levelling data, gravity measurements and older distance and angle measurements.

These measurements and calculations result in coordinates and heights for geodetic points.
