Randolph Glacier Inventory - A Dataset of Global Glacier Outlines, Version 1

The Randolph Glacier Inventory (RGI) is a global set of glacier outlines; it is intended as a snapshot of the world’s glaciers. This data set provides a single outline for each glacier and is produced in coordination with the Global Land Ice Measurements from Space (GLIMS) initiative.The RGI is not suitable for measuring glacier-by-glacier rates of area change, but can be used to estimate glacier volumes, rates of elevation change at regional and global scales, and cryospheric responses to climatic forcing.

Glacier mapping data are contributed to both GLIMS and the RGI from the glaciological community. RGI is produced by the Working Group on the Randolph Glacier Inventory and Infrastructure for Glacier Monitoring, a body of the International Association of Cryospheric Sciences (IACS). This data set is updated approximately annually.

Glacier outlines are distributed as Shapefiles. Hypsometric data (CSV files) and gridded auxiliary data (GeoTIFFs) are also available. All RGI data are packaged globally and by region, with regions based upon the Global Terrestrial Network for Glaciers.

兰多夫冰川名录（Randolph Glacier Inventory, RGI）是一套全球冰川轮廓数据集，旨在提供全球冰川的现状快照。本数据集为每一条冰川提供唯一轮廓，其编制工作与全球陆地冰川太空测量（Global Land Ice Measurements from Space, GLIMS）计划协同推进。兰多夫冰川名录不适用于逐条冰川测算面积变化速率，但可用于估算冰川体积、区域及全球尺度的高程变化速率，以及冰冻圈对气候强迫的响应。

冰川制图数据由冰川学界向GLIMS及兰多夫冰川名录共享提交。兰多夫冰川名录由国际冰冻圈科学协会（International Association of Cryospheric Sciences, IACS）下属的兰多夫冰川名录与冰川监测基础设施工作组编制，本数据集约每年更新一次。

冰川轮廓以Shapefiles格式分发，同时还提供海拔分层数据（CSV文件）与网格化辅助数据（GeoTIFF文件）。所有兰多夫冰川名录数据均按全球及区域范围打包，区域划分依据全球陆地冰川监测网络（Global Terrestrial Network for Glaciers）标准。
