Abstract:
An automated unstructured grid generation system from raw LiDAR data for inundation
analysis of urbanized and suburban areas is developed. With this system, it becomes
possible to perform detailed inundation prediction easily and quickly after a LiDAR
measurement is carried out, whose accuracy is much higher than the conventional GIS
(Geographic Information System). This system is applicable to regions where there are
no GIS data regarding detailed building arrangements. We applied the developed system
to the measured LiDAR data, simulated the inundation process, and compared the results,
with and without a vegetation model.
