2016 GSA: Introduction to Structure from Motion (SfM) Photogrammetry for Earth Science Research and Education short course

Geological Society of America Annual Meeting Short Course, Denver, CO

525. Introduction to Structure from Motion (SfM) Photogrammetry for Earth Science Research and Education

Sat., 24 Sept., 9 a.m.–5 p.m., CCC, Room 110

Instructors: Edwin Nissen, Colorado School of Mines; Ramon Arrowsmith, Arizona State Univ.; Christopher Crosby, UNAVCO

Abstract: Structure from Motion (SfM), a photogrammetric technique that uses overlapping images to construct 3D surface models, is quickly emerging as a valuable research and education tool in geodesy, geomorphology, structural geology, and related disciplines. Images can be collected with a standard consumer-grade camera, making SfM a low-cost tool that compliments other 3D imaging technologies, such as terrestrial and airborne laser scanning (LiDAR). SfM can be collected from a hand-held camera or an airborne platform such as an aircraft, tethered balloon, kite, or UAS (unmanned aerial system), enabling 3D imaging of features ranging in size from decimeters to several kilometers. This one-day course will provide faculty, students, and professionals with an introduction to SfM technology, data collection and processing, and examples of science and educational applications. A combination of lectures and hands-on demonstrations of SfM equipment and data processing will be used.


Agisoft PhotoScan (commercial software, demo/trial version will be used in the course)

CloudCompare (open source software)
