Personal profile

Personal profile

Norman Kerle is currently Adjunct Professor of Geoinformatics for Disaster Risk Management (tenure track) in the ITC’s Earth Systems Analysis department.  He received Masters degrees in geography from the University of Hamburg (Germany) as well as from the Ohio State University (US), and a PhD in geography (volcano remote sensing) from the University of Cambridge, UK (2002).

His research in volcanology started with project work in Costa Rica in 1994, followed by disaster research in the Philippines (1996). A focus on remote sensing developed during a project at NASA's Goddard Space Flight Centre in 1997, followed by extensive work on a multi-national project in Nicaragua (1998-2001). Since then he has moved into more methodological work related to hazards, risk and disaster damage assessment with multi-type geodata, in addition to landslide research and quantitative geomorphology, frequently with object-oriented analysis methods. He is leading the ITC object-based image analysis research group (www.itc.nl/OOA-group).Another current research project focuses on the assessment of post-disaster recovery with remtoe sensing image analsyis and macro-economic agent-based modelling.

In September 2016 Norman Kerle chaired the GEOBIA conference, hosted by the University of Twente/ITC (read more).



Norman Kerle is coordinating the ITC’s contribution to 2 FP7 projectsRECONASS (Reconstruction and Recovery Planning: Rapid and Continuously Updated Construction Damage, and Related Needs Assessment), and INACHUS (Technological and Methodological Solutions for Integrated Wide Area Situation Awareness and Survivor Localisation to Support Search and Rescue Teams). Central to both projects is a research focus on UAV-based structural damage mapping. Previously he worked on EC-funded projects SAFELANDAIDA and GARNET-E.



He is recently led a working group on understanding and influencing volunteers of the COST Action Mapping and the Citizen Sensor, with a specific focus on collaborative/crowdsourced image-based damage mapping.


Professor Kerle also serves as Associate Editor of Remote Sensing and editor of Natural Hazards and Earth Systems Sciences.



His professional affiliations include the European Geosciences Union (EGU), the American Geophysical Union (AGU), the International Society for Photogrammetry and Remote Sensing (ISPRS), and the Remote Sensing and Photogrammetry Society (RSPS). He is a member of Sidney Sussex College at Cambridge University, and a fellow of the Cambridge Philosophical Society.

He has served as external PhD thesis examiner, as reviewer for UNESCO World Heritage Site applications, and referee for international prizes and research funding proposals, such as the Prince Sultan Bin Abdulaziz International Prize for Water, the European Commission's Horizon 2020, the Belgian research programme for Earth Observation STEREO II/III, the Austrian Climate and Energy Fund, the Norwegian Research Council, the Romanian Geoscience Research Council, and the Kazakhstan National Center of Science and Technology.

He is the winner of the 2011 Lloyd's Science of Risk prize in the Natural Hazards category (read more).
