Traditionally geodesy is the science of the measurement and the mapping of the Earth’s surface. Since the surface is mainly shaped by the Earth’s gravity field the classical definition includes the Earth’s gravitational potential. Observing the Earth's figure, the orientation and rotation as well as the gravity field, geodesy today provides spatial and temporal patterns of geophysical processes within the Earth system such as sea-level rise, tides, melting of continental ice masses, changes in global water circulation and in the atmosphere or deformations of the solid Earth. Consequently, the Geodesy Division covers activities on the whole spectrum of modern geodetic Earth system modelling from the measurement systems to the investigation of geophysical processes.

Geodesy Cartoon Competition – Turn Science into Smiles

Geodesy is the science of measuring the Earth’s shape, gravity field, and rotation. What if we could make it exciting, fun, and easy for everyone to understand? That’s exactly why the International Association of Geodesy (IAG) and its Global Geodetic Observing System (GGOS) launched the Geodesy Cartoons initiative: to bring geodesy closer to the public through visually engaging and humorous illustrations. The first Geodesy Cartoons were born from the creative mind of Riccardo Barzaghi, a geodesist and professor at the …


EGU Campfire Geodesy – Share Your Research – 12th Edition

We are excited to announce the 12th edition of Geodesy Campfire – Share Your Research in November. The Geodesy EGU Campfire Events “Share Your Research” give (early career) researchers the chance to talk about their work. We have two exciting talks by our guest speakers, Amin Shakya and Vivek Yadav Kumar. Below, you can find the details of the topics awaiting us. We will have time to network after the presentations. Please join us on Zoom on Sept 11th from …


Highlights at IAG Scientific Assembly 2025 – What you need to know

It is almost time for the scientific assembly of the International Association of Geodesy (IAG), an association of the International Union of Geodesy and Geophysics (IUGG). The EGU Geodesy Division and the IAG have worked together for many years. For example, the IAG has been the main sponsor of the Geodesy Reception at past EGU General Assemblies. Besides this, the IAG coordinates global geodetic research, develops standards, supports international collaboration, and maintains essential geodetic infrastructure and services. And, every four …


Bits and Bites of Geodesy – Trilateration on Vacation: How GNSS Locates You

Summer vacations are finally here! Like every year, many of us are ready to travel and explore new and exciting destinations. And of course, the GPS on our phones will be an indispensable travel companion! Did you know that GPS (or GNSS) positioning is one of the traditional geodetic techniques? Come along to discover how this technique can find your location in the world and the various applications of GNSS positioning! First, what is GNSS? While we often say “GPS” …
