[M-TT35] HIGH-DEFINITION TOPOGRAPHY AND GEOPHYSICAL DATA ANALYSIS

Sun. May 20, 2018 1:45 PM - 3:15 PM A03 (Tokyo Bay Makuhari Hall)

convener:Yuichi S. Hayakawa(Center for Spatial Information Science, The University of Tokyo), Christopher A Gomez (Kobe University Faculty of Maritime Sciences Volcanic Risk at Sea Research Group), Shigekazu Kusumoto(富山大学大学院理工学研究部(理学)), Chairperson:Gomez Christopher(Kobe University), Hayakawa Yuichi, Kusumoto Shigekazu

High-definition, or high-resolution data of earth surface topography and geophysical properties have become widely available for better understandings of the earth surface processes and dynamics. Here in this session, we accept discussions on high-definition topographic and geophysical data, including its theory, acquisition, archiving, processing, modeling and analysis. The approaches may include applications of, but not limited to, laser scanning, SfM-MVS photogrammetry, GNSS positioning, SAR interferometry, multi-beam sonar, geomagnetics and electromagnetics sensors based on terrestrial (fixed or mobile) and aerial (UAV or manned airborne) platforms.
