The DDE-Outcrop3D working group will soon depart for Europe on a digital capture tour of classic geological sites.

In January 2023, the DDE (Deep-Time Digital Earth Big Science Program) Outcrop3D Group and IUGS agreed to cooperate and plan to start digitizing “The First 100 IUGS Geological Heritage sites” in June. The project will include 11 IUGS geological sites in Europe and 10 IAS post-conference outcrops. “The First 100 IUGS Geological Heritage Sites”, to be released in 2021, is an important milestone in the world's geological research history. This collaboration aims to protect better and promote these geological sites.
