Randolph冰川编目（RGI）是一套全球冰川轮廓图，是世界冰原以外冰川的缩影。它为每个冰川提供了大约 2000 年的单一轮廓，以及一组属性和其他相关辅助信息。冰川轮廓图以 Shapefiles 的形式发布。还提供水文数据和属性（CSV 文件）以及元数据（json）。所有 RGI 数据均按全球和区域（由全球陆地冰川网络 (GTN-G) 冰川区域定义）打包。RGI 不适用于测量逐个冰川的面积变化率。不过，它可以用来估算冰川体积、区域和全球范围内的海拔变化率以及冰川对气候作用力的反应。RGI 7.0 版是由国际冰冻圈科学协会（IACS）的 “Working Group on the Randolph Glacier Inventory (RGI) and its role in future glacier monitoring--Randolph冰川编目（RGI）工作组及其在未来冰川监测中的作用”开发的。冰川学界向全球陆地冰川卫星监测计划（GLIMS）数据库提供冰川测绘数据。然后提取 GLIMS 中的冰川轮廓子集并进行再处理，生成 RGI。", "ds_source": "

The Randolph Glacier Inventory (RGI) is a global set of glacier outlines intended as a snapshot of the world’s glaciers outside of ice sheets. It provides a single outline for each glacier from approximately the year 2000, as well as a set of attributes and other relevant auxiliary information. Glacier outlines are distributed as Shapefiles. Hypsometric data and attributes (CSV files) and metadata (json) are also available. All RGI data are packaged both globally and by region (as defined by the Global Terrestrial Network for Glaciers (GTN-G) Glacier Regions). The RGI is not suitable for measuring glacier-by-glacier rates of area change. However, it can be used to estimate glacier volumes; rates of elevation change at regional and global scales; and glacier responses to climatic forcing. RGI version 7.0 was developed by the “Working Group on the Randolph Glacier Inventory (RGI) and its role in future glacier monitoring” of the International Association of Cryospheric Sciences (IACS). The glaciological community contributes glacier mapping data to the Global Land Ice Measurements from Space (GLIMS) database. A subset of the glacier outlines in GLIMS are then extracted and reprocessed to produce the RGI.
