Invited talk by Peggy Aggouri and Anthony Stefanidis.

Title: Crowdsourcing Geographic Information

Abstract: Technological advancements and Web 2.0 capabilities have resulted in the proliferation of Volunteered Geographic Information (VGI), such as OpenStreetMap (OSM), and Ambient Geographic Information (AGI), such as social media content. The integration of such content with traditional geospatial datasets offers tremendous opportunities, especially when it comes to responses to disasters and other emergency situations. Yet, this integration remains challenging, as these data are often non-curated, and their spatial distribution, thematic attributes, reliability and accuracy often deviate substantially from established standards. In this presentation we will discuss such issues, and will present representative novel analysis capabilities as they emerge for the geospatial community.

Bio: Prof Peggy Agouris is Professor and Dean of the College of Science at George Mason University. She is also the Director of the Center of Earth Observing and Space Research, one of the largest research centers at GMU. She received her Diploma in Engineering from the National Technical University of Athens, Greece, and her M.S. and Ph.D. from the Dept. of Civil and Environmental Engineering and Geodetic Science, The Ohio State University. Prior to joining George Mason University in 2007, Dr. Agouris was with the Swiss Federal Institute of Technology in Zurich (1993 – 1995), and the Department of Spatial Information Engineering, University of Maine (1996 – 2006). Her research interests include the automation of processes for spatiotemporal information extraction from digital imagery, change detection, and the integration of remote sensing and digital image processing and analysis within geospatial information systems. She has received more than $28 million in external research funding. She is the recipient of a CAREER award from the Computer and Information Science and Engineering Directorate of the National Science Foundation (NSF). Her work has been supported by further grants and contracts from NSF, the National Geospatial-Intelligence Agency (NGA), NASA, National Reconnaissance Office (NRO), Army TEC, BAE Systems, USGS, and others. Dr. Agouris has authored more than 100 articles in journals, books, and conference proceedings in the image analysis and computer science literature. She has also edited 3 books on digital image analysis for geospatial applications as well as two journal special issues. For her scholastic and research achievements Dr. Agouris has received the 1996 Talbert Abrams Award, the 1990 Leica Photogrammetric Fellowship Award, and the 2009 President’s Best Paper Award (3rd), all from ASPRS. She has also received the 1993 Duane C. Brown Jr. Award from The Ohio State University, as well as the 1998 College of Engineering Outstanding Faculty in Research Award, and the 2001 Dean’s Award of Excellence, both from the University of Maine. Prof Agouris serves on the board of the prestigious United States Geospatial Foundation and has served as chair of various national and international conferences, including (among others) the National Conference on Digital Government Research, the invitational National Science Foundation Workshop on “GeoSpatial and GeoTemporal Informatics”, and IEEE’s Workshop on “Spatial and Spatiotemporal Data Mining”. She also has chaired various working groups of the ISPRS. Dr. Agouris has supervised numerous Ph.D. and M.S. theses, and several of her advisees are already faculty members in various national and international institutions.

Prof Anthony Stefanidis is Professor and Chair of the Dept. of Geography & Geoinformation Science at George Mason University, USA, and the Director of Mason’s Center for Geospatial Intelligence. He holds an undergraduate degree from the National Technical Univ. of Athens (Greece) as well as an M.Sc. and a Ph.D. degree on Digital Image Analysis from the Ohio State University. He did a Post Doc at the Swiss Federal Institute of Technology, Zurich. His areas of expertise include the geosocial analysis of social media feeds, the analysis of digital imagery and video, spatiotemporal information modeling and analysis, and sensor networks. His current research activities are funded by IARPA, the National Geospatial-Information Agency (NGA), Draper Lab, Air Force, and the Army Geospatial Center. His past research activities include projects funded by NSF, NGA, NASA, the USGS, and the European Union, with total budgets of approximately $6.5 millions. In addition to his research activities he is teaching courses in geosocial analysis, image and video analysis, geospatial intelligence, and spatial statistics. Dr. Stefanidis is a member of the Academic Advisory Board of the US Geospatial Intelligence Foundation (USGIF). Prof Stefanidis has co-edited three books, one on image analysis for GIS applications, and two on geosensor networks. He has also edited a journal special issue, and authored or co-authored numerous articles in journals and fully refereed conference proceedings. His work has been featured in various international professional publications. He has also served as reviewer and panelist for NSF, as chair or program committee member for various conferences and workshops, and on the editorial board of the journal ‘Photogrammetric Engineering & Remote Sensing’. For his scholastic and research achievements, he has received the 1988 R. Altenhofen, the 1988 D. Brown, and the 1992 Leica scientific awards, and is a member of the Phi Kappa Phi Honor Society. Dr. Stefanidis has also received a 1998 Young Author Award by the International Society for Photogrammetry & Remote Sensing, the 2003 Early Career Research Award by U. Maine, the 2009 President’s Award for Best Paper (3rd Place) by the American Society for Photogrammetry & Remote Sensing. In 2012 he received, jointly with Drs. Croitoru and Crooks, the 2012 Academic Research Award by the US Geospatial Intelligence Foundation (USGIF).
