Talk Title:
Everyday Geospatial: New Technologies Anyone Can Afford for 3D Field Scanning, Point Cloud Processing, Rock Mass Characterization, & Slope Stability
Abstract:
Geospatial includes remote sensing 3D imaging technologies such as Lidar, photogrammetry, and multispectral and thermal imaging. These technologies can produce high resolution 3D point clouds, from which point cloud processing software is used to extract detailed and in some cases automated rock mass characterization and slope stability outputs. When I started in this field in the early 2000s, 3D imaging and point cloud processing was expensive and time consuming. Lidar scanners cost $100k-$200k, a Lidar survey required numerous surveyed ground control points, and point cloud processing was a manual and time-consuming process. This limited its use to companies that could afford the time and expense. Today, high resolution registered point clouds can be obtained in minutes using iPhone lidar or smartphone pictures, and semi-automated point cloud processing procedures in open-source software are now routinely used to extract rock characterization information. Photos from inexpensive drones can produce very high quality point clouds of large areas, and these surveys can be repeated to monitor degradation and movement. In this Jahns lecture I will discuss modern everyday geospatial tools that are transforming many aspects of applied geology, and give examples of the step by step process involved to go from field imaging to final rock mass characterization and slope stability. This includes some modern AI approaches in several areas. I also mention an online class I teach on rock fractures that includes everyday geospatial skills, where students conduct their own field scanning and point cloud processing in the area where they live.
Biography:
Dr. John Kemeny has over 40 years of experience in the applied geoscience fields through a career that has included working at a geomechanics consulting company, post-doc at the Lawrence Berkeley National Lab, 33 years as Professor at the University of Arizona, and co-founder of a successful startup company that became a world leader in vision-based rock fragmentation measurement software and point-cloud based rock mass characterization software. He earned BS degrees in geology and math from the University of California Santa Barbara in 1977, ME and PhD degrees focusing on rock mechanics from the University of California Berkeley in 1982 and 1986. He began his career in the Department of Mining and Geological Engineering at the University of Arizona in 1989, retiring as Emeritus Professor in 2022. At the University of Arizona Dr. Kemeny published over 170 papers, gave over 80 invited technical talks and workshops, and graduated 15 PhD and over 50 masters students, with research and teaching focused on rock mechanics, slope stability, rock fracture mechanics, numerical simulation in rock mechanics, and developing 3D imaging and sensing technologies for geotechnical applications. In 1998 he co-founded Split Engineering with three students, a spinoff company focused on new technologies for measuring rock fragmentation and point cloud processing software for slope and underground stability. The company had offices in the US, Chile, Peru, South Africa and Australia and was acquired by Hexagon Mining in 2019. Since retiring from the University of Arizona, Dr. Kemeny has been involved with integrating AI into the applied geology fields, to help combat the increasing hazards due to climate change.
