面向三极科学的三维可视化系统应用研究

南极、北极和青藏高原作为地球的"三极"是全球变化的敏感区和研究热点.随着天空地一体化对地观测技术的快速发展,三极时空信息呈现出海量、高时效、多维度的大数据特征.但由于缺乏有效的可视化手段,这些数据很难被非科研人员理解和认知.如何面向不同人群,快速直观地展示三极最新科学发现所产生的时空数据,已成为数据可视化研究迫切需要解...

Application research of 3D visualization system for three poles scientific discovery

As the “three poles” of the Earth，the Antarctic，the Arctic and the Qinghai-Tibet Plateau are sensitive regions and research hotspots of global change. With the rapid development of the sky-ground integration ground observation technology，the three poles spatiotemporal information presents large-scale，high-efficiency，multi-dimensional big data features. However，due to the lack of effective visualization methods，these data are difficult for non-scientists to understand and recognize. How to quickly and intuitively display the latest data of space-time three poles for different groups of people has become a bottleneck of visual analysis. Based on the characteristics of three poles scientific data and results，this research designs a prototype system （called three poles sphere） based on an open source framework for the discovery of three poles scientific discoveries，focusing on some key technologies such as the distributed data storage，automatic data preprocessing，three-dimensional development engine，screen interoperation，automatic generation of analysis results. Meanwhile，the three typical scenarios are taken as examples to show the scientific discovery of the three poles vividly and intuitively.They are the amplification effect of the Arctic，the comparison and correlation between freezing/thaw of snow and ice the three poles and the impact of the three poles on the climate in East Asia. This system can help managers and the general public to understand the research results such as the changes in the ecological environment of the three poles and the impact on China’s weather and climate，and also have a demonstration role in the display of relevant information in the field of geosciences.
