CALFIN Subseasonal Greenland Glacial Terminus Positions, Version 1

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.

本数据集涵盖1972年至2019年格陵兰岛冰川末端与冰川流域的形状文件（shapefile）。此类矢量数据依托陆地卫星（Landsat）1至8号的卫星影像，通过崩解前缘处理机（Calving Front Machine，CALFIN）这一自动化处理流程生成；该流程借助神经网络从入海冰川的卫星影像中提取冰川崩解前缘。
