This dataset includes measurements of protodune and barchan height, length and migration on both Mars and Earth. Earth measurements were calculated from high resolution Terrestrial Laser Scans (TLS) of bedforms migrating through time in coastal and desert regions. Raw point cloud data can be found at Nield et al. (2023a; 2023b; 2025a; 2025b). Mars measurements were calculated from High-Resolution Imaging Science Experiment (HiRISE) imagery.
