In recent years, with the acceleration of the melting of the Antarctic ice sheet, a large amount of ice melt has formed on the surface of the ice sheet from 2000 to 2019. It is of great significance to study the material balance of the Antarctic ice sheet to deeply understand the spatial-temporal distribution and dynamic changes of the melt water on the Antarctic ice sheet. This data set is based on Landsat7 and landsat8 images with 30 m spatial resolution from 2000 to 2019. By using normalized water body index, Gabor filtering and morphological path opening operations, the ice melt grid data set is generated, and the grid water body mask is converted into vector data in ArcGIS. This data set is based on the 250m ice surface melt water data set of the Antarctic ice sheet melting area (Alexander Island, Antarctic Peninsula) from 2000 to 2019 extracted from Landsat images. The time is concentrated from December to February (Southern Hemisphere summer)

File naming and required software

The data set format is vector (SHP) and grid (TIF)
Data processing method: Based on Landsat7 and landsat8 images with 30m spatial resolution from 2000 to 2019, this data set uses normalized water index, Gabor filtering and morphological path opening operations to generate ice melt grid data set, and converts the grid water mask into vector data in ArcGIS. Vector (.Shp) / grid (.Tif) data can be directly loaded into mainstream GIS software (such as ArcGIS, QGIS).
