Discover the basics of Geodesy and geodetic data! Geodetic data, from Global Navigation Satellite Systems (GNSS)to gravity measurements, play a crucial role in societal application as well as Earth sciences, including hydrology, glaciology, geodynamics, oceanography, and seismology. Are you curious about what these data can (and cannot) tell us?

This short course offers a crash course in core geodetic concepts, giving you the insights, you need to better understand the advantages and limitations of geodetic data. In 60 minutes, we will take you on a ride across geodetic datasets. We'll start with reference frames, the core definition of any global coordinates, then move on to the workings of GNSS and its possible pitfalls, before landing on measurements of the Earth's gravity field and what they can tell us about the changes in Earth system and climate. None of these endeavours would be possible for a single scientist or a single country alone, so we will end with a glimpse into the international collaboration needed to sustain these diverse geodetic datasets, and products, and how users can find and access them.

While you won’t become a full-fledged geodesist by the end, you’ll walk away with a clearer picture of how to use these datasets across various fields. No laptop or prior knowledge of geodetic data analysis is required. Led by scientists from the Geodesy Division, this course is open to all — whether you frequently work with geodetic data or are simply curious about what geodesists do. Expect lively discussions and practical insights, and for geodesists in the room, a chance to learn what non-geodesists actually need when working with geodetic data.
