Data for 'Controls on Ice Cliff Distribution and Characteristics on Debris-Covered Glaciers'

This dataset contains ice cliff, pond, debris, glacier and crevasse zone outlines (as shapefiles) derived for the study 'Controls on Ice Cliff Distribution and Characteristics on Debris-Covered Glaciers'. They were outlined from 14 Pléiades multi-spectral images (see Methods and tables in corresponding manuscript and SI) acquired at the dates indicated in the corresponding folder names. The majority of the Pléiades stereo-pairs used were provided by Etienne Berthier via the Pléiades Glacier Observatory (PGO) initiative of the French Space Agency (CNES). The remaining images were acquired through the CNES ISIS Programme.

本数据集包含为研究《覆盖碎屑冰川的冰崖分布与特征控制因素（Controls on Ice Cliff Distribution and Characteristics on Debris-Covered Glaciers）》所提取的冰崖、冰面水塘、碎屑、冰川及冰裂缝带的形状文件（shapefile）。上述要素轮廓由14景普莱阿德斯（Pléiades）多光谱图像解译得到，图像成像日期标注于对应文件夹名称中，详细方法与数据表格参见对应论文及补充材料。本研究使用的多数普莱阿德斯立体像对由Etienne Berthier通过法国国家空间研究中心（CNES）发起的普莱阿德斯冰川观测站（PGO）项目提供。剩余图像则通过法国国家空间研究中心ISIS项目获取。
