Benjamin Herfort

Benjamin Herfort is researcher at HeiGIT and Heidelberg University. In his PhD he has investigated questions of representation and data quality in OpenStreetMap from the perspectives of humanitarian and machine learning-assisted mapping in order to map what is not mapped. In his research and work he is furthermore dealing with the temporal evolution of OpenStreetMap data, MapSwipe and information from social media.

Benjamin works as a product owner at HeiGIT where he is developing open source tools and methods that incorporate geographic information systems for disaster management, humanitarian aid and climate action.

An academic insight on the functioning of fAIr
Anna Zanchetta, Benjamin Herfort, Marta Magnani
