G53A:
Earth Science Research and Change Detection Using Multitemporal Lidar and SfM II


Submit an Abstract to this Session


Session ID#: 57960

Session Description:
Capturing Earth’s surface in 3D, LiDAR and structure-from-motion (SfM) have found widespread application and driven fundamental advances in the Earth sciences and are becoming more prevalent as technology and accessibility improve. Repeat collections of these datasets are currently used extensively throughout the disciplines of geomorphology, to study processes including morphodynamics, mass wasting and earthquake surface displacement and damage, and forestry, to study wildfire effects and carbon flux. They have also been used selectively in volcanology and cryosphere science. We aim to bring together researchers from different Earth science sub-disciplines who use LiDAR and SfM to conduct change detection research. While the challenges of using repeat data for monitoring Earth surface dynamics and many of the techniques for quantifying change are highly cross-disciplinary, the research questions in each of these sub-disciplines are unique. Session will explore the aims and outcomes of studies using repeat LiDAR and SfM throughout the Earth sciences.
