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…

Derivation of an OSM graph with TMC LCL traffic information to provide real time traffic services
Increasing traffic, especially in urban areas, leads to more and more infrastructural bottlenecks and congestion inside transportation networks. The aim is therefore to use existing transport networks as efficiently as possible. Current traffic and incident reports from the Traffic Message Channel (TMC) are an important source of information to provide further services in the context…
