A STUDY ON THE DEVELOPMENT OF THE URBAN WATERS FLOODING SIMULATION SYSTEM USING UNITY3D

摘要

Of urban natural disaster damage, the internal waters flooding brings on great damage on residential areas and big economic losses, so it should be promptly coped with. This study thus sought to develop the urban internal waters flooding simulation system using the open source-based Unity3D engine in order to promptly cope with the internal waters flooding thus minimizing damage. The target area was determined as Seoul where population is densely clustered with a huge number of facilities, and a virtual base map was constructed using the aerial images and DEM data. The internal waters flooding data consisted of coordinates and flooding depth. If the simulation function is implemented, a cube-shape 3D object will be created in each coordinate of data, and the material color value (RGBA) is applied according to the legend classified based on random criteria. And, the height value of the cube's Scale.z property is changed and visualized according to data flooding depth values. The urban internal waters flooding simulation system can identify the output in diverse angles and is intuitive, compared to the existing 2D output. The situation control tower, where the proposed system is applied, is expected to more accurately identify and cope with the internal waters flooding situation so as to provide support for efficient decision making.
