3D Field Trip to Greece – Exploring 3D GIScience in one of the most exciting geological settings
Our students learned how multiple 3D geodata sensor systems (LiDAR, UAVs, GNSS) can be used to capture and analyze the geomorphology and geology of one of the most exciting geological areas, the Peloponnese in Greece. Together with the geology students from the University of Stavanger more than 30 young researchers explored the area around the…

Geo-reCAPTCHA: Crowdsourcing large amounts of geographic information from earth observation data
With the Geo-reCAPTCHA we present a new concept for crowdsourcing of vast amounts of geoinformation by micro-mapping tasks. The paper can be downloaded free of charge (until 22 May 2015). In our study we investigated the possibilities and limitations of capturing building footprints via Geo-reCAPTCHA based on remote sensing imagery. We could analyze more than…

History Scanned in 3D – Jupiter Column of Ladenburg
Within our interdisciplinary collaborative research project MUSIEKE (Multidimensional Perceptibility of Cultural Heritage) the Jupiter Column (“Iupittergigantensäule”) of Ladenburg was scanned in 3D and in very high detail for the first time. Our colleagues from the IWR (FCGL Group of Hubert Mara) performed the measurement campaign. In this report (in German) the SWR 4 radio station…
