North, Ryan High-resolution elevation models and orthophotos of Larsen B glaciers extracted from 1960s imagery Mendeley Data This dataset contains two DEMs and corresponding orthophotos of Larsen B tributary glaciers (Jorum, Crane, Mapple, Melville and Flask Glaciers), Antarctic Peninsula, representing surface elevations in December 1968. The DEMs were created with structure-from-motion photogrammetry using aerial imagery that is freely available from the Polar Geospatial Centre, UMN (https://www.pgc.umn.edu/data/aerial). These are raw DEMs and orthophotos projected to WGS84 Antarctic Polar Stereographic (EPSG::3031). Resampling, filtering of outliers, smoothing, interpolation or other data editing can be applied at one's discretion. The Crane Area DEM covers the Jorum, Crane, Mapple and Melville and is 3.2 m spatial resolution with a standard deviation of ± 15.2 m relative to stable terrain in REMA v2 2021 data (https://www.pgc.umn.edu/data/rema) or ± 24.6 m relative to ICESat-2 points. The Flask Area DEM (which covers to Flask Glacier) is 13.3 m spatial resolution with a standard deviation of ± 21.5 m relative to stable terrain in REMA v2 2021 data or ± 21.6 m relative to ICESat-2 points.
