摘　　要：北极作为地球“三极”之一,蕴藏丰富资源,是全球变化研究的热点区域,其海冰变化对航道开通和生态保护具有重要意义。然而,现有三维虚拟地球(3D GIS)系统无法直接支持非规则格网的数据可视化,限制了北极航道信息服务能力。针对这一技术瓶颈,本研究提出了一种将非规则格网数据自动转换为规则格网数据的方法。同时,研发了基于Cesium的海冰数据三维可视化系统,实现了长时间序列非规则格网海冰数据在三维虚拟地球系统中的自动加载和可视化。性能评估结果表明:该方法具有较高的精度和效率,研发系统能够高效和直观展现北极冰情变化,可为船舶航行规划提供重要冰情信息。The Arctic,as one of Earth's“Three Poles”,is abundant in resources and serves as a key focus in global change research.Changes in sea ice within this region are highly significant for the opening of navigational routes and the preservation of ecological systems.However,existing 3D GIS systems lack the capability to di⁃rectly visualize irregular grid data,thereby restricting their capacity to support Arctic passage information servic⁃es.To address this technical challenge,this study proposes a method to automatically transform irregular grid data into regular grid data.Additionally,a Cesium-based three-dimensional visualization system for sea ice data has been developed,enabling the automatic loading and visualization of long-term irregular grid sea ice data within a 3D virtual Earth environment.Performance evaluations demonstrate that the proposed method achieves high levels of accuracy and efficiency,and the developed system effectively and intuitively depicts Arctic sea ice changes,providing critical ice condition information to support ship navigation planning.
