The four-day Great Geodetic Excursion is organized every 2 years alternately by one of the chairs of the study program "Geodesy and Geoinformation". It gives practical impressions of different fields of work in geodesy. This time our chair was responsible for the organization.
We looked at the huge areas of open-cast lignite mining in Lusatia and also dealt with the consequences of open-cast mining - expropriations, resettlements, re-use, renaturation. We visited various institutions such as research institutes, universities, companies and construction sites. In Freiberg, we learned about mine surveying and the great researchers who worked there over the centuries. In Görlitz and Bautzen, we admired the historic old towns and deal with the challenges of structural change. In Dresden, we dealt with current urban development. As a crowning finale, we drove into the 110-meter-deep former tin mine in Ehrenfriedersdorf.
