Research Onvisualization of Large Scale and Complex Spatiotemporal Data
After more than fifty years of development,satellite remote sensing technology has made tremendous progress.With the improvement of remote sensing data acquisition capabili-ties,remote sensing data has become diversified and massive from multiple sources.However,the development and research of visualization technology has been relatively slow,resulting in a relative lag in the efficiency and performance of remote sensing data in visualization applica-tions.There are many shortcomings in traditional map services based on pre generated tiles,which are difficult to meet the professional application needs of large-scale complex spatiotem-poral data in display,layer attribute configuration,and spatial analysis and calculation.By defi-ning a framework for dynamic parallel visualization of remote sensing big data,adopting real-time rendering image interactive visualization process,we study the spatiotemporal base big data dynamic parallel visualization model and user visualization view model,and propose a solution for large-scale and complex spatiotemporal data visualization.
