Dear colleagues,

The International Association of Geodesy (IAG) will hold its Scientific Assembly in Rimini (Italy) on
September 1-5, 2025.

The IAG Scientific Assembly is a quadrennial event, held in the middle of the periods between IUGG
General Assemblies. After the virtual meeting in Beijing in 2021, we are happy to have a full in-person
meeting in Italy.

Under the headline “Geodesy for a changing environment” we have set up 14 symposia (including
three joint symposia) covering topics of all IAG Commissions, Inter-Commission Committees, Projects
and Services. 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.

With one dedicated symposium on outreach, data management, and networking with science and
policy, the increasing importance of geodesy for a broad variety of societal topics will be emphasized.

In addition, we selected four Highlight Sessions covering four topics that are at the forefront of
geodetic research and having a high impact on society. Presentations in these Highlight Sessions will
be partly by invitation only and partly by selecting appropriate contributions from the submitted
abstracts.

All details on abstract submission, registration, and all other organizational information can be found
on the web site https://eventi.unibo.it/iag2025

Abstract submission fee is 40 Euro per abstract.

The IAG provides the opportunity for young scientists from developing countries to receive a travel
award in order to encourage them to be a part of IAG Scientific Assembly 2025. Please, refer to the
web site https://www.iag-aig.org/awards/travelgrant for the detailed rules and procedures to apply
for an IAG travel award.

IAG Symposia Series
All participants of the IAG Scientific Assembly are invited to publish their research presented at the
Assembly (oral and poster) in the IAG Symposia Series by Springer. This series is now fully Open-Access
with the fees for Open-Access covered by IAG. Thus, the first author shall be the participant in the
Assembly. The papers will be online shortly after each paper is accepted following a peer review
process, so that they do not have to wait for the entire volume to be completed. The deadline for
submitting manuscripts to the IAG Symposia Series is set to November 30, 2025.

We are looking forward to see you in Rimini for the IAG Scientific Assembly 2025.
