Subglacial Topography Training Image Database

<p>This database contains elevation data for 166 topographic training images. These training images should be cited as Yin et al., (2022). The file contains a&nbsp;40,000 x166 matrix, where each column contains one TI. Each column should be reshaped to 200x200. The resolution is 500 m, and each TI is 100x100 km². The elevation data were obtained from ArcticDEM (Porter et al., 2018) and IBCSO (Arndt et al., 2013).&nbsp;</p> <p>Arndt, J. E., Schenke, H. W., Jakobsson, M., Nitsche, F.
