Last September, about 400 delegates gathered in Florence, Italy from all over the world, to attend the 11th International Symposium on Digital Earth (ISDE11).
The Opening Plenary session was held in the historic Salone dei Cinquecento at Palazzo Vecchio. This included a celebration ceremony for the 20th anniversary of the International Symposium on Digital Earth which was initiated in Beijing, China in November 1999 by the Chinese Academy of Sciences (CAS).
The event endorsed and approved a new Declaration by the International Society for the Digital Earth, The 2019 ISDE Florence Declaration. After 10 years in the making, this declaration lays the path to a new definition of Digital Earth that will be finalized in the first months of 2020.
