Fahrner, Dominik; Lea, James; Brough, Stephen; Abermann, Jakob; Mair, Douglas

This data set was created by Dominik Fahrner (Institute for Risk and Uncertainty; Department of Geography and Planning, University of Liverpool) using the Google Earth Engine Digitisation Tool (GEEDiT; Lea, 2018) and is based on Landsat 4 - 8 satellite imagery. It comprises annual tidewater glacier margins (digitised in September of each year)  for 206 Greenlandic tidewater glaciers for the period 1984 - 2017, and corresponding centerlines.
