On behalf of the Department of Physics and Astronomy (DIFA) and the Department of Civil, Chemical, Environmental, and Materials Engineering (DICAM) of the Alma Mater Studiorum – Università di Bologna we would like to invite you to attend the IAG 2025 Scientific Assembly, to be held from 1 to 5 September, 2025, in Rimini, Italy.

The theme of the Assembly is “Geodesy for a changing environment” to be developed within the domains of interest of the four IAG Commissions, namely: Reference Frames, Gravity Field, Rotation and Geodynamics, and Positioning and Applications.

The scientific assembly provides a unique opportunity for the international community to meet, propose and discuss topics where geodetic science plays a considerable role. The theme of the assembly draws geodesists’ attention to impacts of environmental variations/changes, increasingly severe extreme events of different nature and to developing strategies apt to capture the onset of abrupt changes in the Earth system.

We are looking forward to receiving your important contributions and to welcoming you in Rimini for the IAG 2025 Scientific Assembly.
