Special Lecture: UAV Remote Sensing for Hydro-Morphological monitoring
Summary. Unmanned Aerial Vehicles (UAV) are becoming a widely used measurement tool in geomorphology and hydrology due to their cost, flexibility and ease of use. Due to the high spatio-temporal resolution of UAV data it became possible to evaluate the continuum instead of relying on individual samples in the field of fluvial morphology. In this talk, a semi-automatic workflow will be introduced to perform UAV-based hydrometric measurements at reach scale considering RGB as well as thermal imagery. More specifically, particle tracking velocimetry (PTV) is used to measure river surface velocities. Image-based 3D reconstruction is considered to retrieve the bathymetry as well as topography in case studies with sufficient observation conditions. And eventually discharge is calculated combining all measurements. Several case studies are chosen to demonstrate the vast applicability of UAV remote sensing for hydro-morphological monitoring.”
About the Speaker
Dr. Anette Eltner is a PostDoc at the Institute of Photogrammetry and Remote Sensing at the TU Dresden, Germany. She received her Ph.D. degree (Dr.-Ing.) in 2016 at the TU Dresden, Germany, investigating photogrammetric methods in soil erosion studies. And she received her Diploma degree in Geography with minors in Photogrammetry and Remote Sensing, Soil Sciences, and Hydrology in 2010. Her research interests include developing methods for geomorphological and hydrological monitoring, UAV photogrammetry, developing methods in Spatio-temporal high-resolution topography, image processing in geographical applications, implementation of low-cost sensors using micro-computers/-controllers, and erosion processes in fragile landscapes. She has authored and co-authored 39 scientific papers, 28 of which appeared in peer-reviewed international journals. In 2017, she received the prize of the German Geomorphology Association for best PhD thesis. She is (guest-)editor of different journals in the field of remote sensing and geomorphology.
