LiDAR-derived Digital Terrain and Surface Models (DTM/DSM) and flood simulation models were used to determine exposure and vulnerability of building to various flood hazard scenarios caused by extreme rainfall events in a river basin in Mindanao, Philippines. The methodology consist of (i.) generating a database of buildings from the DTM and DSM; (ii.) generation of flood depth and hazard maps through the use of a flood simulation model; and (iii.) spatial overlay analysis utilizing the building database and flood maps to determine a building?s exposure and vulnerability. This study highlights the importance of combining high spatial information from LiDAR with simulation model to generate informative maps showing the exposure and vulnerability of buildings to flooding.
