Geodetic Information Systems and Projects
International Earth Rotation and Reference Systems Service (IERS)
This service provides information on astronomical and global terrestrial reference systems and the data on the rotational behavior of the earth.
GNSS Data Center of BKG
The GNSS Data Center collects the data of almost 200 globally distributed GNSS permanent stations for various international, European and national projects.
Information system for the BKG stations of the Integrated Geodetic Reference Network of Germany (GREF) - in German only -
Information system of the project for establishing the European Combined Geodetic Network (ECGN)
Information system for the European Vertical Reference System (EVRS)
The web project EVRS includes information about this coordinate reference system and related projects as, for example, the realization of the EUVN and EUVN-DA.
Information system for European Coordinate Reference Systems (CRS-EU)
The system contains the description for national European and pan-European coordinate reference systems for position and height and transformation parameters to pan-European Coordinate Reference Systems and transformation for single points.
Detailed information on CRS-EU
Atmospheric Attraction Computation Service (ATMACS)
This is a joint service of BKG and DWD and provides time series for correction of atmospheric mass attraction in Gravimetry.
Detailed information on ATMACS
Absolute Gravity Database (AGrav) of BKG and BGI
The international database AGrav is a joint service of BKG and BGI to store and provide the results of absolute gravity measurements worldwide.
The projects “D-A-CH Geoid” and “European Alps Geoid” – improved cross-border height determination in the region of the European Alps
