资源简介:
使用Landsat 8地表反射率的数据和SNOMAP算法制备FSC的参考数据集,将该数据集作为训练样本区域FSC真值,从而建立训练样本区域FSC与基于MODIS地表反射率产品的雪被指数NDSI之间的线性回归模型,得到2021年30m×30m中巴经济走廊积雪分布数据集,数据类型为GRD栅格数据。数据量为5.95 MB。
A reference fractional snow cover (FSC) dataset was generated using Landsat 8 surface reflectance data and the SNOMAP algorithm. Taking this dataset as the ground truth of FSC in the training sample areas, a linear regression model was established between the FSC values of these areas and the Normalized Difference Snow Index (NDSI) derived from MODIS surface reflectance products. Subsequently, the 30 m × 30 m snow cover distribution dataset of the China-Pakistan Economic Corridor in 2021 was produced. The data type is GRD raster data, with a total data volume of 5.95 MB.
