Opis

This research explores the benefits of merging side-view Structure-from-Motion data with conventional top-view LiDAR data to create a novel multi-source views (MSV) topographic description of complex urban topographies. Using this new MSV approach, two case studies were carried out for the 2003 flood event in Kuala Lumpur, Malaysia and the 2011 flood event in Ayutthaya, Thailand. Adopting the MSV data as the basis for describing the urban topography, the numerical simulations provide a more realistic representation of complex urban flood dynamics and revealing specific features like flood watermarks identification and helping to develop improved flood-protection measures.

O autorze

Vorawit Meesuk is a PhD candidate in hydroinformatics for urban flood modelling at UNESCO-IHE and TU-Delft, the Netherlands. He holds a background MSc degree in Remote Sensing and GIS technologies (2003) from Khon Kaen University, Thailand. His PhD research focuses on the topic of applying computer vision and photogrammetry techniques to create better topographical data by merging different sources and difference viewpoints to enhance 2D flood simulation for complex urban cities. Besides doing research, he organised the Ayutthaya workshop in a joint effort with ADB, UNESCO-BANGKOK, in 2014. He also guided MSc students and gave GIS and coupled 1D-2D modelling lectures at UNESCO-IHE. Currently, he works at (HAII/MOST) as a Head of Observation and Telemetry Section, whose responsibilities are to provide and maintain telemetry systems for monitoring weather conditions and water-level changes in over 700 stations in Thailand and neighbouring countries.
