Bio

Michael E. Hodgson received the B.A. from the University of Tennessee in 1980, the M.S. from the University of South Carolina (with coursework at the University of Georgia) in 1984, and the Ph.D. from the University of South Carolina in 1987. Prior to his tenure at the University of South Carolina he was Team Leader at the Oak Ridge National Laboratories, Assistant Professor at the University of Colorado, and Geographer at Henningson, Durham, and Richardson. In addition to his research and teaching in the USA he has served as Visiting Professor and taught GIScience courses at the University of Salzburg University (Austria) and the University of Padova (Italy).

Research 

My research interests are broadly in geographical information science with particular interest in the use of remote sensing approaches (e.g. LiDAR) for environmental problems. My funded research has focused on the development of innovative approaches and techniques for rapidly or more accurately extracting information from imagery and geospatial data. Recent research has utilized survey methods, cognitive studies, and GIS-based modeling for probing theoretical questions and pragmatic solutions to geographic problems. For instance, how do the state and counties emergency operations centers utilize geospatial approaches in disaster response and recovery (survey methods)? How does a trained image interpretation expert recognize objects and patterns on aerial imagery (cognitive studies)? And how can we model this cognitive image interpretation process and implement in an automated solution? What is the appropriate design and implementation for a 4-dimensional (space and time) satellite-sensor image collection model (GISci-modeling)? How can we reliably and rapidly, with estimates of confidence and uncertainty, map information from airborne LiDAR data sources?

My current research interests utilize GIS-based modeling approaches to environmental problems and the use of sUAS imagery and LiDAR data for mapping and monitoring the landscape.
