资源简介:
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.

兰道夫冰川清单(Randolph Glacier Inventory, RGI)是一套全球性的冰川轮廓数据集,旨在刻画全球冰川的整体状态快照。该数据集为每一条冰川提供单一轮廓,并与星载全球陆地冰测量(Global Land Ice Measurements from Space, GLIMS)计划协同制作。兰道夫冰川清单不适用于逐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。 冰川测绘数据由冰川学界向GLIMS与兰道夫冰川清单共同贡献。RGI由国际冰冻圈科学协会(International Association of Cryospheric Sciences, IACS)下属的兰道夫冰川清单与冰川监测基础设施工作组负责编制,该数据集约每年更新一次。 冰川轮廓以Shapefile格式分发,同时还提供了高程-面积统计数据(以CSV文件存储)以及网格化辅助数据(GeoTIFF格式)。所有兰道夫冰川清单数据均按全球及区域进行打包,区域划分依据全球陆地冰川监测网络(Global Terrestrial Network for Glaciers)标准。
