Web-based 3D Visualization Of Large-scale Meteorological Radar Data

In recent years,with the vigorous development of meteorological detection technology and geographic information science(GIS),analysis and research in the field of meteorology are also continuously progressing,and the monitoring and early warning of severe convective weather are becoming more and more timely and accurate.With the rapid development of computer technology and network technology,web visualization applications have gradually expanded from two dimensions to three dimensions.How to quickly and efficiently complete Web-based three-dimensional visualization has become a research hotspot.Web-based visualization of radar data facilitates the analysis and sharing of meteorological radar data,which enhances and promotes the development of various meteorological applications.So far,due to technical,software,and hardware limitations,most meteorological data visualization research is limited to two-dimensional or small-scale three-dimensional visualization analysis,while large-scale meteorological radar data three-dimensional visualization has made little progress.With the development of network transmission and WebGL,the visualization of large-scale 3D models based on the Web has tended to be mature.These models often have a large number of patches and rich texture images to be processed,which can meet the data volume requirements of largescale meteorological data.Based on this,this paper proposes to apply the large-scale modelbased visualization technology to the visualization research of large-scale meteorological radar data to improve the visualization efficiency.In this paper,based on the analysis of the data structure of the meteorological radar data and the data structure of the model data,the model data construction of the three-dimensional meteorological radar data is completed,and the meteorological radar product data is used to study the visualization effect and efficiency.Then use the meteorological radar data model construction plan,data service technology and Web related technology to design a three-dimensional visualization platform for meteorological radar data,and complete the three-dimensional visualization application of meteorological radar three-dimensional data and related data.Based on the above research content,this paper conducts research on 3D visualization of large-scale meteorological radar data based on the Web.By constructing a 3D Tiles model of the 3D data of meteorological radars,the efficient web visualization of 3D data of large-scale meteorological radars is completed.Using this solution,the visualization of 3D isosurface data of weather radar and the national composing data of weather radar is completed.Finally,a weather radar data visualization platform is developed in combination with Web related technologies.From this,we can draw the following conclusions:(1)The visualization solution by constructing a 3D Tiles model of 3D data of meteorological radar can apply the advantages of the 3D model to the web visualization of 3D data of large-scale meteorological radar,improving the efficiency of 3D visualization;(2)The solution proposed in this article can be combined with Web technology to realize the visualization application of large-scale meteorological data,and provide technical and method support for large-scale expression of meteorological data in the network environment.
