Flood visualization using CityGML based 3D models

The main objective of this research was to develop a methodological workflow to create 3D building models in CityGML standard from airborne LiDAR point cloud. 

City GML (City Geographic Markup Language) is an OGC (Open Geospatial Consortium) based data model framework, in XML (eXtensible Mark-up Language) that enables storage and exchange of 3D models which can be used for diversified applications.

The project also aims at demonstrating the applicability of the proposed 3D CityGML models for flood simulation/modelling. The output from the model can be used by the decision makers to prioritize flood evacuation measures and flood risk management
