System Development Of Weather Modification Spatial Visualization Simulation

Weather modification is effective in serving agricultural production,alleviating water shortage,preventing and mitigating disasters,ecological environment protection and security of government events.As long-term strategic plan for the implementation of the party and the state council,to adapt to the weather modification work faces new situation and new requirements,strengthen the figure in the ability of ecological civilization,disaster prevention,disaster mitigation,national development and reform commission and the China meteorological administration jointly compiled the national weather modification development plan(2014-2020),overall planning the development of weather modification operations included government security engineering.At the same time,China meteorological administration and the national center for human development clearly put forward the task of speeding up the information construction of weather modification business in the 13 th five-year plan.At present,the domestic means of artificially influencing the weather mainly include aircraft rainfall enhancement operations,ground rainfall,and flood control operations.Among these operations,Among them,there are rain-increasing operations on the ground operations,rockets and flood prevention operations on the silhouette rockets,and rain and flood prevention operations on the silhouette smokers.The figure and ground plane assignments are based on spatial 3D scene,the traditional two-dimensional GIS technology can not be scientific and effective for the expression of figure process,so need to develop to be able to figure and ground plane three-dimensional visual simulation for process of 3D GIS system,in order to meet the needs of the development of weather modification operations.The study in a large domestic 3D GIS platform EV-Globe platform,on the basis of fully integrated study area and the class of remote sensing image data,vector electronic map with large scale data,terrain elevation data and figure job site,model and information data,USES the multi-source data fusion technology,data integration management rendering technology and dynamic simulation technology,build the figure and ground plane space visualization simulation system.The system has realized the efficient and fast integrated management of high-resolution remote sensing data,the 3D model data and the weather modification working data.Rapid construction of simulation 3D geography scene of weather modification work area;The simulation of 3d visualization of the process of adding rain of the aircraft and the ground operation,hail of the ground operation.The system effectively solves the urgent demand of the 3D visualization simulation display and analysis of national weather modification business.It's not only to improve the ability of weather modification work,and meets the strategic development demand of the big data informationization and visualization of weather modification in the new era.
