Stammler, Melanie; Blöthe, Jan Henrik; Cusicanqui, Diego; Ebert, Simon; Bell, Rainer; Bodin, Xavier; Schrott, Lothar: Pléiades imagery based digital elevation models and quantified surface change for (debris-covered) glaciers and rock glaciers in the Dry Andes of Argentina (30ºS, 69ºW; 2019, 2022, 2023, 2024, 2025) [dataset]. PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.988303 (dataset in review)
Abstract:
The dataset encompasses digital elevation models (DEMs, 1 m spatial resolution) and quantified surface changes for (debris-covered) glaciers and rock glaciers in Rodeo basin for the years 2019 and 2022-2025. The DEMs are derived from (tri)stereo panchromatic Pléiades imagery using Ames Stereo Pipeline and are clipped to the cryogenic landforms in Rodeo basin as mapped in the National Inventory of Glaciers (Argentina) with a bounding box with a minimum 500 m distance to the landform polygon. Vertical surface change of 19 glaciers, 3 debris-covered glaciers and 58 rock glaciers is determined by coregistering the above-described DEMs and generating DEMs of Difference at a spatial resolution of 1 m. Rock glacier velocities of 47 rock glaciers for which we have data for all time periods are determined by feature tracking on the panchromatic Pléiades imagery at a resolution of 5 m.
