Google Earth Engine ——Hyperion高分辨率的高光谱（200个波段）数据集

Hyperion is a high resolution hyperspectral imager producing 220 unique spectral channels ranging from 0.357 to 2.576 micrometers with a 10-nm bandwidth. The instrument operates in a pushbroom fashion, with a spatial resolution of 30 meters for all bands and a standard scene width of 7.7 kilometers.

This dataset contains level 1A radiance images, radiometrically calibrated and orthorectified. The SWIR bands have a scaling factor of 80 and the VNIR bands have a scaling factor of 40 applied.

• VNIR bands (B008-B057, 426.82nm - 925.41nm): L = Digital Number / 40
  
• SWIR bands (B077-B224, 912.45nm - 2395.50nm): L = Digital Number / 80
  

Note that bands B001-B007, B058-B076, and B225-242 are not calibrated, have no valid values and are not included into EE assets. See the detailed spectral coverage information.

This is a preview dataset; only a portion of the data from the original source have been downloaded so far. The remainder are in progress.

Hyperion是一个高分辨率的高光谱成像仪，产生220个独特的光谱通道，范围从0.357到2.576微米，带宽为10纳米。该仪器以pushbroom方式运行，所有波段的空间分辨率为30米，标准场景宽度为7.7千米。

该数据集包含1A级辐射度图像，经过辐射度校准和正射处理。SWIR波段的缩放系数为80，VNIR波段的缩放系数为40。

VNIR波段（B008-B057，426.82nm - 925.41nm）。L = 数字编号/40

SWIR波段（B077-B224，912.45nm - 2395.50nm）。L = 数字编号 / 80

请注意，B001-B007、B058-B076和B225-242波段没有经过校准，没有有效的数值，不包括在EE资产中。参见详细的光谱覆盖信息。

这是一个预览数据集；到目前为止，只有一部分来自原始资料的数据被下载。其余的正在进行中。
