利用World View-Ⅱ遥感影像高空间分辨率和高波谱分辨率的数据优点,结合Aster数据波段互补的优势,进行南极大陆边缘拉斯曼丘陵Fe信息提取研究。研究结果表明,使用World View-Ⅱ与Aster数据对比分析的主成分法,提取Fe3+信息,采用World View-Ⅱ与Aster协同数据下的波段运算法,提取Fe2+信息,可以达到优势互补的目的。Fe信息提取结果显示,含铁矿物信息分布区主要集中在混合片麻岩与副片麻岩区域,分别占Fe信息总面积的80.39%和15.73%,与野外调查结果基本一致。
Based on the data superiority of World View-Ⅱ remote sensing imagery with high spatial resolution and high spectral resolution, combined with the advantages of Aster data band complementation, Fe information extraction of the Rathman hills in Antarctic continental margin was studied. The results show that using the principal component method of comparative analysis of World View-Ⅱ and Aster data to extract Fe3 + information and using the band algorithm under World View-Ⅱ and Aster collaborative data to extract Fe2 + information can achieve the purpose of complementarity. Fe information extraction results show that the information distribution area of iron minerals mainly concentrated in the area of mixed gneiss and paragneiss, accounting for 80.39% and 15.73% of the total area of Fe information, respectively, which is basically consistent with the field survey results.
