| 摘 要： | 本文评价了运用ASTER和LANDSAT ETM+数据进行岩性制图的性能。分别利用ASTER数据不同波段区图像及其组合,以及ETM+数据进行岩性分类,并探讨了将ASTER和ETM+数据叠加在一起进行了岩性分类; 利用现有地质图对所有分类结果进行了定量评价。结果表明,ASTER数据不同波段的岩性识别能力不同,并且较ETM+数据能更准确地识别岩性。更重要的是,把ASTER与ETM+数据结合在一起进行岩性分类,可获得比用任一数据单独分类更高的分类精度,表明二者的光谱特征具有一定的互补性。

| Abstract: | The performance of lithologic mapping using both ASTER and LANDSAT ETM+ data was evaluated in this paper. Lithologic classifications using different spectral regions of ASTER data, different combination of them, and ETM+ data were performed respectively, especially using all ASTER and ETM+ bands. The results showed that different spectral regions of ASTER data produced different mapping accuracies. ASTER data obtained better performance in lithologic classification than that of using ETM+ data. Classification with all ASTER and ETM+ bands combined achieved high overall accuracy and Kappa coefficient, compared to those obtained with ASTER data or ETM+ data alone, which may indicate that both data provide complementary information for lithologic discrimination. |
