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