The Chair of Geosensors and Engineering Geodesy (GSEG) represents geodetic core subjects related to 3d capturing of the real world, establishing the geometric relations between digital models and reality, and monitoring changes.
In research, we aim specifically at the development of sensors, sensor systems and data analysis methods for monitoring - and where possible - controlling of critical processes, especially in relation to natural hazards, changes in the environment and innovative construction processes. Our main focus is on the prediction and evaluation of the data quality, on the optimization of measurements and analytic procedures for specific application fields, and on the estimation of the relevant information from large amounts of raw data. The research has a strongly experimental and interdisciplinary character. It builds on numerical simulations, parameter estimation, machine learning, lab experiments and fieldwork. Our teaching and outreach are closely related to this research but also cover more established surveying and geodetic metrology.
Two years ago, Russia launched its war of aggression against Ukraine. One direct consequence of the conflict is the destruction of buildings and infrastructure. Now an exhibition in the ETH Main Building entitled “ETH with Ukraine” is showing how buildings, facilities and the environment in Ukraine can be protected or restored.
This year, six doctoral students from the Department of Civil, Environmental and Geomatic Engineering are honoured for their outstanding achievements: four of them receive ETH medals, two the Culmann Prize. Big congrats!
Spatial planning in the underground is becoming increasingly important. As part of the pioneering project "Digital Underground", an international research team led by D-BAUG professors Martin Raubal and Andreas Wieser is developing a 3D map of the underground in Singapore. The digital twin will help to save time and costs in construction and increase worker safety. The mapping initiative has model character and could also find applications in Switzerland in the future.
