FAYETTEVILLE, Ark. – Jackson Cothren and Jason Tullis, both professors of geography in the U of A's Department of Geosciences and both members of the Center for Advanced Spatial Technologies, are guests for Monday's Department of Crop, Soil and Environmental Sciences Seminar Series.

Their presentation is "Photogrammetric and remote sensing in emerging geospatial unmanned aircraft systems (UAS)."

They speak at 3:30 p.m. in Plant Science Building Room 009. The seminar is open to everyone on campus.

Cothren, who has been director of the Center for Advanced Spatial Technologies since 2003, has also been director of the Arkansas High Performance Computing Center since 2015. He earned his bachelor's degree in applied mathematics from the U.S. Air Force Academy in 1985, and a master's degree (2000) and Ph.D. (2004) in geodetic science and surveying from Ohio State University. His research focuses on geodetic and photogrammetric adjustment computations, uncertainty propagation in sensing systems, non-traditional sensor modeling and computer vision applied to overhead images.

As director of CAST, his interests have broadened to the general application of spatial data science to a wide variety of environmental and social problems.

Tullis earned his bachelor's degree in geographic information systems (GIS), remote sensing and botany from Brigham Young University, and his master's degree (2001) and Ph.D. (2003) from the University of South Carolina. His research focuses on remote sensing and GIS-assisted decision support for ecosystem services and on the application of provenance information in geographic problem solving.
