Digital Elevation Models of Tweedsmuir Glacier 1950-2018

<p>This dataset contains digital elevation models (DEMs)&nbsp;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 &quot;Amplification of Surface Topography during Surges of Tweedsmuir Glacier&quot; for sources). All DEMs have been co-registered to ArcticDEM (Porter et al., 2018) using Shean et al (2016)&#39;s open-source tool&nbsp;<em>demcoreg</em>.</p> <p>&nbsp;</p>
