Study on Forest Fire Visual Analysis Method for Extinguishing Command in Virtual Environment
Aiming at the demand of forest fire fighting command,the information required for the command,such as geographical environment,meteorological conditions,forest resources and forest fire behavior are comprehensively analyzed,and the data visualization visual analysis method in the virtual forest fire environment is designed and realized.Wang Zhengfei-3D mixed cellular automata model is used to simulate the process of forest fire spread and the difference time method is adopted to predict the forest fire spreading behavior.The change of environmental data in different interest domains is captured in real time,and the multi-view panel and overlay layers are combined to construct the visual analysis module of fire field information.The process of forest fire spread in different scenes is simulated by adjusting the environmental parameters of virtual forest scene,and the information of the fire field is visually analyzed.The experimental results show that the visual analysis method can not only more accurately predict the forest fire spread behavior under certain conditions,but also more comprehensively describe the fire field information.
