LBA-ECO CD-34 Hyperion 30-m Surface Reflectance, Amazon Basin: 2002-2005
简介
该数据集包含 20 幅由 EO-1 卫星 Hyperion 传感器以 30 米分辨率采集的多光谱地表反射率图像，涵盖 2002 年至 2005 年期间的整个亚马逊盆地。所有图像均已转换为 GeoTiff 格式以供分发。相应的 ENVI *.hdr 文件作为配套文件包含在内，其中包含图像投影和波段信息。
使用 ENVI 软件对选定的多光谱图像进行处理，如 Chambers 等人 (2009) 所述。未校准波长的波段和光谱响应较低的波段被移除，留下通常为 196 个波段的光谱子集（某些图像的波段更少）。使用可变反射率波段的二维散点图开发了云掩模，以突出显示作为感兴趣区域 (ROI) 的云，从而可以掩盖云和云边缘。然后将去条纹算法应用于图像，以减少垂直柱之间平衡的差异。使用大气校正算法 ACORN 在 1.5pb 模式下（AIG-LLC，科罗拉多州博尔德）计算此平衡图像的表观表面反射率。使用相应的高级陆地成像仪 (ALI) 卫星图像对图像（20 张中的 18 张）进行地理配准。
