L8 Biome Cloud Validation Masks

The U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center in Sioux Falls, SD developed a cloud validation dataset from 96 unique Landsat 8 images called the “L8 Biome” dataset. These images were selected from various locations around the world, and are evenly divided between eight unique biomes and three different cloud cover categories. The images are curated by biome and cloud cover to reduce bias in any one region or cloud cover density. While these validation images were subjectively designed by a single analyst, they provide useful information for quantifying the accuracy of clouds flagged by various cloud masking algorithms. Each mask is provided in ENVI binary format, and includes all bands from the original Landsat Level-1 data product (GeoTIFF), and its associated Level-1 metadata (MTL.txt file).美国地质调查局（U.S. Geological Survey, USGS）位于南达科他州苏福尔斯的地球资源观测与科学（Earth Resources Observation and Science, EROS）中心，从96张独特的陆地卫星8号（Landsat 8）影像中构建了名为“L8 Biome”的云验证数据集。这些影像选自全球多个区域，均匀分布于8种独特生物群系与3种不同云量类别中。该数据集按照生物群系和云量进行筛选整理，以降低单一区域或云量密度带来的偏差。尽管这套验证影像由一名分析师主观设计选取，但它可为量化各类云掩膜算法识别云的准确率提供有效参考依据。每个掩膜文件以ENVI二进制格式提供，同时包含原始陆地卫星1级数据产品的所有波段（GeoTIFF格式）及其配套的1级元数据（MTL.txt文件）。
