This data set is based on the normalized difference snow index (NDSI) data of MODIS version 6. The traditional algorithm is used to estimate the snow cover rate (FSC). The MODIS / Terra am satellite and MODIS / Aqua PM satellite monitoring are used to process the cloud pollution and estimate the snow cover rate under the cloud step by step through four steps to obtain the daily snow distribution of China Pakistan Economic Corridor Dataset.

This data set is composed of two sub data sets, including the ice lake and glacier distribution data sets of the permafrost area and key areas of China Pakistan Economic Corridor in * * years. The spatial range of the study area is 34 ° – 42 ° n, 73 ° – 82 ° e, including key drainage basins such as the kaleqing River, Hongza River, Gaizi River and nubula river. The research scope includes glaciers, snow, water and other typical surface types in alpine areas. Glaciers and ice lakes are selected as the target surface types for extraction. The surface types and ranges in this data set are based on the GCS  WGS  1984 projection coordinates. The documents include FID, shape, glims  ID, GLC  name, area and peri Meter), class (u name), center of mass position coordinates (x-coordinate, y-coordinate) and other information. Taking Landsat 8 oli remote sensing image as the data source, through the object-oriented classification method, the glacier and ice lake classification and distribution data set in the key areas of China Pakistan Economic Corridor are completed.

Based on the remote sensing data MODIS surface temperature data product, the desertification degree of China Pakistan Economic Corridor is evaluated by using the difference index of desertification (DDI), and the normalized vegetation index (NDVI) and albedo are used as the monitoring indexes. By constructing the albedo NDVI feature space, and using the negative correlation between albedo and NDVI, the DDI formula is constructed to complete the year-on-year desertification of China Pakistan Economic Corridor The thematic data set of desertification classification can directly reflect the desertification degree of China Pakistan Economic Corridor and provide reference for quantitative assessment of desertification severity. The data can provide basic data support for the regional scientific research of China Pakistan Economic Corridor.
