分析评价多角度CHRIS数据在土地覆盖分类中的性能。分析了不同地物的多角度光谱特征,运用不同角度的CHRIS数据及其组合进行土地覆盖分类。结果表明,不同地物在不同角度上的光谱特征不同,不同角度图像的分类精度不同,而运用多角度CHRIS图像可得到比单角度图像更高的分类精度,但要得到最佳的分类结果,需要选择合适的多角度图像组合。 更多还原

【Abstract】 The availability of multi-angle CHRIS(Compact High-Resolution Imaging Spectrometer) imagery with high spatial resolution provides new opportunities for more accurate land cover classification than ever.In this paper,multi-angle CHRIS data were evaluated in land cover classification,using CHRIS mode-5 images acquired over an agricultural area.The multi-angle spectral features of different land cover types derived from CHRIS images were first analyzed.The land cover classifications were the perfor...
