Gravity Information System (SIS)

This project is finished with this beta-version.

The operation of the information service SIS and the g-extractor could no longer be guaranteed due to IT security aspects. So we were forced to do this Service until further notice.

On the internet pages of the BKG (https://www.bkg.bund.de/DE) you will find further information about geodesy / gravity.
