Dense point cloud of the Marmolada Glacier: alignment of Pre-Detachment (20220702) and Post-Detachment (20220708)

Using data acquired from two independent commercial drone surveys, we generated high-resolution digital models of the Marmolada Glacier before and after the collapse event of July 3, 2022, in northeastern Italy, which resulted in the tragic loss of eleven lives.

We thank the Civil Protection Department of the Autonomous Province of Trento (Gruppo UAS Dipartimento Protezione Civile, Foreste e Fauna; PAT Servizio Antincendi e Protezione Civile) for providing the videos recorded in July 2022, and Dr. Ing. Cristian Ferrari, President of SAT (Società Alpinisti Tridentini), for the video recorded on July 2, 2022, the day before the collapse.
