"Measuring the World" is the title of a book by Daniel Kehlmann from 2005. Although the term "measuring" is broadly defined, there is a scientific field that literally deals with the recording of geometric and semantic information of the earth: geodesy with its numerous sub-disciplines. The information to be recorded can relate to the entire globe, for example when it comes to determining the exact shape of the earth and its gravitational field. However, mapping of the land surface, e.g. the shape of the terrain or its use, is just as much a part of this field as the detailed measuring of buildings or industrial plants.
The IGP teaches and researches in many fields of geodesy. Due to the integration into the Faculty of Architecture, Civil Engineering and Environmental Sciences at the TU Braunschweig, many interesting interdisciplinary questions arise both in teaching and research. Our focal points are:
This involves the precise acquisition of (dynamic) geometric data of buildings, for example: how does a bridge respond to load, is a tower leaning, is the slope shifting?
Remote Sensing and Photogrammetry:
"A picture is worth a thousand words" - this saying can also be applied here. Images taken by satellites or other platforms such as airplanes or flying robots help us to capture and analyze both geometric and semantic information about the earth's surface or even individual buildings.
In this subfield of geodesy, the aim is to efficiently visualize and analyze spatial data. Only in this way the greatest possible benefit can be derived from them.
