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.
