Dr. Sisi Zlatanova is Associate Professor at the GIS Technology Section, Delft University of Technology, and currently leads a theme group on 'Geo-information for Crisis Response'. Her research interests include the use of spatial technologies in emergency response, in particular where special attention is given to the third dimension: 3D object reconstruction, 3D data structures and geo-databases, 3D spatial relationships (topology) and 3D visualization (VR and AR). Sisi Zlatanova is currently serving as chair of the ISPRS WG IV/8 'Spatial Data Integration for Emergency Services, 2004-2008', and author of numerous publications on 3D modeling and technology for emergency response. Dr. Jonathan Li is Associate Professor at the Department of Geography, University of Waterloo, Canada. From 2001-2006, he was Assistant/Associate Professor and the Director of GroVELab at Ryerson University in Toronto. Jonathan Li was the Conference Secretary of MMT'2004, and is currently serving as Co-Chair for ISPRS WG IV/8 'Spatial Data Integration for Emergency Services, 2004-2008'. His research interests include remote sensing, 3D urban modeling, intelligent object extraction from imagery, spatial data integration for disaster management, and WebGIS.Zlatanova is the author of 'Geospatial Information Technology for Emergency Response (ISPRS)', published 2008 under ISBN 9780415422475 and ISBN 0415422477.
