Geologists use topographic data on a daily basis for various tasks such as geomorphology interpretation, slope stability analysis, geologic and hazard mapping, environmental delineation, and design layout. This short course will delve into the collection methodology of this three dimensional topographic data and present examples of geologic analyses of it. The hands-on portion of the class will include data collection via UAV photogrammetry, and various forms of lidar collection including terrestrial, mobile, and airborne techniques. Classroom discussions will be held that provide insight into how the data is processed and analyzed for engineering geology applications.

Michael Olsen, College of Engineering Dean’s Professor, Oregon State University:
MICHAEL J. OLSEN, Ph.D. is the College of Engineering Dean’s Professor in the School of Civil and Construction Engineering at Oregon State University. He obtained BS and MS degrees in Civil Engineering from the University of Utah and a PhD in Structural Engineering from the University of California, San Diego. At OSU he teaches courses in geomatics topics such as 3D laser scanning and imaging, digital terrain modeling, and geographic information systems. He is also the Editor in Chief for the ASCE Journal of Surveying Engineering as well as the President of the Surveying and Geomatics Educators Society (SaGES). His current areas of research include geomatics technologies, algorithm development, 3D visualization, rapid reconnaissance, and geospatial hazard mapping , monitoring, and analysis, Dr. Olsen has extensive experience collecting and analyzing high quality geospatial data from terrestrial laser scanning and UAS platforms for monitoring, mapping, and post-disaster reconnaissance of damages for a variety of hazards including earthquakes, tsunamis, landslides, rockfalls, and coastal erosion. He has participated in reconnaissance teams by either collecting or analyzing data for the following events: 2009 American Samoa, 2010 Maule Chile, 2011 Tohoku Japan, 2010&2011 Canterbury Earthquake Sequence, 2015 Nepal, 2016 Kaikoura New Zealand, 2018 Anchorage Alaska earthquake, and 2019 Hooskenaden landslide in Oregon. He serves as the Technical Director for the NSF Natural Hazards Research Infrastructure (NHERI) RAPID facility, which provides investigators with equipment, software, and support services needed to collect, process, and analyze perishable data from natural hazards events. He is also the Director of the Cascadia Lifelines Program (CLiP), which conducts research that allows Oregon’s lifeline providers to implement value- and cost-informed decisions to mitigate damage to Pacific Northwest infrastructure as the result of Cascadia subduction zone earthquakes. He is also a co-developer of the Oregon Hazards Explorer for Lifelines Program (O-Help, http://ohelp.oregonstate.edu), which is a powerful webGIS platform designed for the engineering community and hosts a wide range of hazard maps for Cascadia Subduction Zone Earthquakes including ground acceleration, liquefaction, landslides, and more.
Bernie Doud, CP, GISP, Project Manager, Aero-graphics:
Mr. Doud’s passion has always been in the geospatial world. This started with maps and aerial photographs in his youth, moved to 3D feature and surface extraction from stereo imagery early in his career, and voraciously forged into aerial LiDAR acquisition and automated surface modeling as the technology has matured. His business strengths include corporate strategy, national LiDAR and imagery program leadership, proposal development, and quality management system implementation. Bernie holds a Bachelor of Science degree in Geographic Information Systems from Brigham Young University and a Master of Business Administration degree in Project Management from City University of Seattle. He is a Certified Photogrammetrist with ASPRS and a GISCI Certified GISP.
Trevor Contreras, L.E.G Landslide Hazards Geologist, Washington Geologic Survey:
Trevor is a Licensed Engineering Geologist with the Landslide Hazards Program at the Washington Geological Survey, where he studies landslides and helps communities understand and mitigate landslide hazards. Currently the Landslide Hazard Program uses lidar data to inventory landslides and alluvial fans throughout Washington State. He has worked for the WGS since 2006 in various positions and in the Forest Practices Division helping foresters understand landslides and evaluate timber harvest proposals. He has used lidar data to make geologic maps and map landslides since 2009. Prior to working for the Survey, he worked for the Washington Department of Ecology, regulating well drilling and water well construction.
Cole Smith, Owner, Elevate UAS:
Shortly after earning a masters in geology from Colorado School of Mines, Cole moved back to Oregon and started Elevate in 2015. Combining his background in geology, remote sensing and GIS, Cole leveraged his unique skill set to the fledgling UAS industry. Elevate delivers project specific remote sensing services using high resolution imagery from RGB, thermal infrared and multi spectral cameras as well as high density LiDAR. This remotely sensed data is processed into high resolution geospatial data products that range from classified point clouds, DEMs, and detailed change detection analysis. Offering services like data collection, post processing, and data hosting, Elevate can bring any project site into a high resolution 3D model. Elevate primarily works with engineering firms and DOTs to help clients better understand how remotely sensed data can lead to a deeper understanding of their project sites.
Adam Booth, Assistant Professor, Portland State University:
Adam M. Booth is a quantitative geomorphologist who works on the role of landslides in landscape evolution. He earned a bachelor’s degree in Physics from Grinnell College, followed by a PhD in Geology from the University of Oregon. After a postdoc at Caltech, Dr. Booth then joined the faculty in the Department of Geology at Portland State University in 2013, where he works at present. In addition, Dr. Booth was recently a Fulbright-National Science Foundation Arctic Research Scholar in Iceland in 2020.
Dr. Booth first began using high-resolution 3D topographic data to automatically identify and map deep-seated landslides based on their distinctive topographic signatures in airborne lidar data. His more recent work has shown that those topographic signatures also encode information about landslide age, which allows approximate dating of hundreds to thousands of prehistoric landslides in a region so that their timing with respect to paleoseismicity and paleoclimate can be analyzed. Over shorter time scales, Dr. Booth also collects and analyzes repeat data from terrestrial or airborne lidar and photogrammetric techniques to measure high-resolution 3D landslide displacements and infer the mechanical processes governing their motion.
