Glacier inventory of the upper Huasco valley, Norte Chico, Chile

Shapefile of the glacier inventory of the Upper Huasco catchment, Chile, that was generated for the following research article: Nicholson, L. I., Marín, J., Lopez, D., Rabatel, A., Bown, F. and Rivera, A.: Glacier inventory of the upper Huasco valley, Norte Chico, Chile: glacier characteristics, glacier change and comparison with central Chile, Ann. Glaciol., 50(53), 111–118, doi:10.3189/172756410790595787, 2010. Glaciers were mapped on the basis of ASTER imagery from 2004, and classifed for the study as clean ice glaciers (1), debris covered glaciers (2) and rock glaciers (3). Additionally, classification following the GLIMS gudeilines (https://www.glims.org/.../GLIMS_Glacier-Classification-Manual_V1_2005-02-10.pdf ) was applied where possible to glacier features on the basis of additional ASTER imagery from 2002 and 2003, and older air photographs.

智利上瓦斯科流域冰川清单的Shapefile数据集，本数据集为下述研究论文制作：Nicholson, L. I.、Marín, J.、Lopez, D.、Rabatel, A.、Bown, F.与Rivera, A.共同发表的《智利北奇科地区上瓦斯科谷冰川清单：冰川特征、冰川变化及其与智利中部的对比》，刊载于《冰川学年鉴（Ann. Glaciol.）》2010年第50卷第53期，页码范围111–118，数字对象标识符（DOI）：10.3189/172756410790595787。冰川解译制图以2004年的先进星载热发射和反射辐射计（ASTER）影像为基础，本研究将冰川划分为三类：洁净冰冰川（1类）、冰碛覆盖冰川（2类）与岩石冰川（3类）。此外，研究尽可能依托2002年、2003年的额外ASTER影像以及老旧航空照片，遵循全球冰川测量系统（GLIMS）分类指南（https://www.glims.org/.../GLIMS_Glacier-Classification-Manual_V1_2005-02-10.pdf）对冰川要素开展分类工作。
