CCWI2017: F73 'A 3D WEB GIS INTERACTIVE VISUALISATION SYSTEM FOR ANIMATED FLOODS'

We present an interactive 3D WebGIS visualisation system that can show animated 3D floods,
terrain, and buildings from a web browser. The system is entirely written in Javascript and using
optimised WebGL technology based on the open source Three.js library. It can be used to view and
deform terrain and flood surfaces in real-time, provided the modelling data are supplied in
standard image formats. Although, in the examples presented below, the .png pictures expressing
flood depth were produced via the CADDIES-2D modelling and simulation framework, the system
can work online in real-time with any kind of flood modelling tool, as long as it provide 32 bits
encoded images in a reasonable time frame. The system can show real-time 3D flood animations
and seems to be simple and flexible enough to be used in future multi-player online serious games
centred on flood.
