This dataset contains digital elevation models (DEMs) of Tweedsmuir Glacier, British Columbia, Canada between 1950 and 2018. DEMs from 1950, 1969, 1974, and 1987 were created using Structure-from-Motion photogrammetry in Agisoft Metashape by Meghan A. Sharp. DEMs from 2000, 2007, 2010, and 2018 were acquired from open-source satellite sources (see "Amplification of Surface Topography during Surges of Tweedsmuir Glacier" for sources). All DEMs have been co-registered to ArcticDEM (Porter et al., 2018) using Shean et al (2016)'s open-source tool demcoreg.
