The centre is headed by Prof. Dr.-Ing. Volker Coors and Prof. Dr.-Ing. Michael Hahn. The Competence Centre Geodesy and Geoinformatics pools research activities concerned with the acquisition and processing of spatial information. Thematically, not only classical surveying tasks are addressed, but specialised methods are developed, to interface with other disciplines.

The expertise embraces a wide range, from sensor technologies over data processing to visualisations. As sensor systems and measurement devices not only classical systems are operated from the surveying, photogrammetry and remote sensing domains, but also ones with new functionality are put into account.

Based on the selection and combination of sensor principles and analysis methods, new and innovative approaches for cooperation in highly interdisciplinary working fields are found. The operated sensors use optical, mechanical or electromagnetic measurement principles. Specially developed camera-assisted visualization techniques facilitate the documentation of a subject’s geometrical and optical properties. Laser scanners make it possible to turn surfaces directly into point clouds, while spectrometers enable the measurement of fine spectral reflective characteristics. Methods from image understanding und pattern recognition are combined for the data analysis. For the capture of position and orientation, GPS devices provide suitable measurements, which can be combined with sensor data from IMUs (inertial measurement units), providing acceleration and rotation rates. Such combinations are the basis for a variety of mobile mapping developments. For applications within buildings, additionally radio-based positioning systems are available. The combination of sensor data for measurements and navigation are typically used for automation tasks in robotics.

Radio-basedpositioning systems are available for applications inside buildings. A combination of sensor data collected for measurement and navigation purposes is generally used for automation tasks and the control of robotic equipment. This makes it possible to identify current states as well as task-critical changes over space and time.

The development of innovative geoinformation methods facilitates the processing of spatial data before implementing them in new contexts. A main focus on 3D geodata infrastructures is put to account for applications in city planning, simulation and mobile navigation. Application-oriented software development is used to enhance geographic information systems and their applications. Furthermore, international collaborations exist for the development and use of open standards.
