30 m resolution lake ice type data set of Qinghai Tibet Plateau, Siberia and alaga river lake region, 2015-2019
In the process of data set production, firstly, the sentinel-1 satellite data is downloaded from GEE platform, and then the hmrf algorithm is used to classify the downloaded data in batches to obtain the grid classification results of different lake ice types. Secondly, the raster data is converted into vector data in IDL. Finally, the vector data is post processed in ArcGIS to obtain the three polar regions from 2015 to 2019 Vector data sets of different lake ice types in the region. The data is in the folder of region, each region has different lakes, named by number, and imported into GIS to obtain the lake ice type of corresponding date.
