High-resolution digital surface modeling (HRDSM) is a powerful tool to help understand geomorphological processes and products in settings ranging from the seafloor to extraterrestrial planetary surfaces. HRDSM is especially useful in deep-water environments shrouded in perpetual darkness, allowing marine geologists to visualize and interpret seafloor panoramas that will never be seen in person by humans. On land, virtual deforestation workflows can reveal geomorphological details such as active fault scarps, sinkholes, and landslide remnants concealed by dense forests. Although data acquisition methods and geologic processes may differ among marine, terrestrial, and extraterrestrial settings, many HRDSM methods initially developed for non-marine applications are potentially useful for seafloor analysis. This presentation will highlight ongoing HRDSM work at the Kentucky Geological Survey's Digital Earth Analysis Lab, including (1) development of an intelligent geomorphic swath tool to geometrically characterize complex topographic systems such as fluvial terrace sequences, (2) quantifying limits to geomorphic change detection using multi-generational and multi-modal digital elevation models, (3) integrating inventory-based statistical models of landslide occurrence with infrastructure information to create risk maps, and (4) more efficiently identifying colluvial deposits on quadrangle scale (1:24,000) surficial geologic maps.

Professional Development Hours:
This webinar counts as 1 Professional Development Hour. The certificate of participation will be issued a day after the presentation.

About the presenter
 
Dr. William C. Haneberg is a research professor in the Department of Earth and Environmental Sciences at the University of Kentucky, where he serves as the state geologist of Kentucky, director of the Kentucky Geological Survey. His career includes 15 years with state geological surveys in New Mexico and Kentucky separated by 17 years as an engineering geology consultant specializing in areas such as geohazard assessment, computational geology, and GIS applications. Before coming to Kentucky in 2016, he was a senior consultant with Fugro in Houston, where he led a multidisciplinary team engaged primarily in integrated site characterizations and geologic hazard assessments for deep-water oil and gas projects around the world. Dr. Haneberg was the 2011 GSA-AEG Richard Jahns Distinguished Lecturer in Engineering Geology, received the 2005 Claire P. Holdredge Award from the Association of Engineering and Environmental Geologists, and is a Fellow of the Geological Society of America. Dr. Haneberg is an author or co-author of well over one hundred technical papers and abstracts. He earned his PhD in geology from the University of Cincinnati in 1989.
