Dr. Mathews’ research expertise is in geospatial data analysis, and use of geographic information systems (GIS) and remote sensing techniques. Specifically, he uses unmanned aerial systems (UAS) as remote sensing platforms to capture high spatial resolution aerial imagery for mapping and analysis. Dr. Mathews has recently worked on externally-funded research projects with Oklahoma State Parks focusing on GIS data collection, analysis, and web mapping , and the Oklahoma NASA Space Grant Consortium/NASA EPSCoR collaborating with Dr. Amy Frazier (Geography) and researchers from the NASA Jet Propulsion Laboratory to quantify urban built-up volume and assess volumetric change in cities with lidar data.
