Daniel R. Unger is an Associate Professor of Remote Sensing and GIS. His current responsibilities at SFA involve teaching, research and service involving the quantification, qualification, mapping, monitoring and management of natural resources via the spatial analysis fields of aerial photo interpretation, digital image processing, GIS and GPS. Prior to coming to SFA he was an Assistant Professor of Natural Resource Measurements within the Department of Forestry at Southern Illinois University where he was involved in teaching, research and service relative to the inventorying, mapping, monitoring and management of natural resources via the fields of mensuration, aerial photo interpretation, digital image processing and GIS.
