Global mapping of lake-terminating glaciers

This dataset is the result of a community effort to identify lake-terminating glaciers in the Randolph Glacier Inventory (RGI) version 7 (RGI 7.0 Consortium, 2023), and is fully described in the related paper, published in Earth System Science Data (Steiner et al., 2026). For a full description of the dataset, including the definition of lake-terminating categories, see either the related paper, or the README in the GitHub repository. Dataset The dataset/ folder has the following structure: dataset/ ├─ contributor_files/ └─ RGI-v7.0-G-{region}/ ├─ RGI-v7.0-G-{region}_{contributor}.csv ├─ csv/ └─ RGI-v7.0-G-{region}_lakeflag.csv ├─ lakeflags/ └─ RGI-v7.0-G-{region}_lakeflag.gpkg └─ outlines/ └─ RGI-v7.0-G-{region}_laketerminating.gpkg Where: contributor_files/ contains all of the original/individual submissions provided by different contributors csv/ contains a comma-separated variable (.csv) file for each RGI region lakeflags/ contains a geopackage (.gpkg) file for each RGI region, with the geometry set to the RGI7 centroid latitude/longitude outlines/ contains a .gpkg file for each RGI region, with the geometry set to the RGI7 outline, but only for glaciers categorized as lake-terminating category 1-3 Each of the files in the dataset folders contains the following fields: rgi_id - the RGI v7.0 ID for the glacier lake_cat - the lake-terminating category for the glacier, as defined below; image_id - the ID of the image that was used to classify each glacier; image_date - the date (or date range) of the image used to classify each glacier; inventory_doi - the DOI of the lake inventory (if used); contributor - the ID of the contributor(s) who classified the glacier notes - any additional notes from each contributor Additionally, the contributor_files/ may have an additional field, auto_term. When running scripts/finalize_csv.py, the column term_type (if included in the .csv) is renamed to auto_term to indicate that scripts/assign_lake_flag.py was run and there was an inventory lake within the buffer around the terminus (auto_term == 2) The .gpkg files contained in the lakeflags/ and outlines/ directories are generated from the .csv files and the RGI outlines using scripts/generate_geopackage.py References RGI 7.0 Consortium, 2023.
