English(EN) D-TINs for Track-Sampled Ice Sheet Surface Reconstruction from Satellite Altimetry Data

新的D-TIN方法改进了卫星数据的冰盖表面重建

作者 PulseAugur 编辑部 · [1 个来源] · 2026-11-11 05:00

研究人员开发了一种名为D-TIN的新方法，用于从卫星测高数据中重建冰盖表面，该数据以稀疏的轨道覆盖为特征。该技术直接在观测位置利用Delaunay三角剖分和重心插值。与克里金法和基于瓦片的多项式插值等现有工作流程相比，D-TIN显著降低了均方根误差，并提供了显著的计算效率提升。 AI
