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.
