New version available: Randolph Glacier Inventory - A Dataset of Global Glacier Outlines, Version 7
The Randolph Glacier Inventory - A Dataset of Global Glacier Outlines, Version 7 dataset is now available through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set is a global set of glacier outlines intended as a snapshot of the world’s glaciers beyond the ice sheets. It provides a single outline for each glacier at approximately the year 2000 as well as a set of attributes and other relevant auxiliary information.
For this version, the quality of outlines in many regions has improved substantially due to the inclusion of new, updated inventory data. Some attributes have been removed or renamed/redefined, while new ones are now available. In addition to the outlines of individual glaciers, outlines of contiguous glacier complexes are now available (“glacier complex" product). New shapefiles of common boundaries of individual glaciers, as well as glacier centerlines, have been added (“intersects" and "centerlines" products). All outlines and attributes are derived exclusively from GLIMS. A new largely automated workflow has been developed to generate the RGI from the GLIMS database, with the code publicly available to ensure reproducibility. Filename conventions have been updated. For more information on the changes made to each glacier region, please refer to http://www.glims.org/rgi_user_guide/05_description_by_region.html.
