NASA landsat Project

This data set contains shapefiles of Greenland’s glacial termini and basins for the years 1972 to 2019. These vector data were created from Landsat 1-8 satellite imagery using the Calving Front Machine (CALFIN) an automated processing workflow utilizing neural networks for extracting calving fronts from satellite images of marine-terminating glaciers....本数据集包含1972年至2019年格陵兰冰川末端与流域的形状文件（Shapefile）。此类矢量数据基于陆地卫星（Landsat）1-8号卫星影像生成，采用冰崩前缘机器（Calving Front Machine，简称CALFIN）这一自动化处理流程；该流程借助神经网络从滨海终端冰川的卫星影像中提取冰崩前缘。
