A Data Model for Integrating GIS and BIM for Assessment and 3D Visualisation of Flood Damage to Building

Abstract

Flood Damage Assessment (FDA) is a key component in modern risk management frameworks providing an effective basis for decision making and the treatment of the risks. Current FDA methods do not consider the distinctiveness of buildings in analysis and therefore, cannot analyse them on a case-by-case basis, which is necessary for a variety of applications like engineering and design evaluation. This is mainly due to the limited input data used in these methods. The information required for such micro-level FDA analysis includes on one hand, complete building information (well-represented in BIM) and on the other hand, flood information that is commonly managed by GIS. While the independent us..
