Statistical Data Analysis And Reseach On WebGIS Visualization

With the progress of science and technology and the wide application of Internet technology,it has become one of the important work contents of statistical departments in various industries to carry out visual analysis of massive data and thereby dig the meaning behind the data.Aiming at the above requirements,this dissertation designs a set of data visualization analysis flow of statistical data,which can carry out visual analysis of the data in specified format,and completes the development of the system.In this dissertation,the main work is as follows:1.the design of the statistical data of data visualization analysis process,in this process based on the detailed design of the system requirements and software architecture,function modules,and complete the system development and testing work.2.In the process of selecting the visual model included in the system,a variety of typical 2D and 3D WebGIS visual models were selected with WebGIS visualization technology as the focus,which enabled multi-dimensional visual analysis of spatiotemporal and geographical data in statistical data and output cartoon-based visual graphics.3.The research integrates the density clustering algorithm with the visualization analysis process,optimizes the visual effect of the visualization results,and solves several engineering problems such as mass data display chaos and slow browser load.
