Geography Colloquium talk on VGI at University of California Santa Barbara (UCSB)

The series of colloquium presentations in the winter term 2014 at the Department of Geography at University of California Santa Barbara (UCSB) was opened by a talk by Alexander Zipf who is a guest at the UCSB Center of Spatial Studies as reported earlier. This talk presented an overview of some of the investigations on the quality and applicability of VGI and how these can be improved at the GIScience Research Group at Heidelberg University. The focus was on OpenStreetMap (OSM) as one of the most successful examples of VGI in Europe.
