This database contains elevation data for 166 topographic training images. These training images were developed by Yin et al., (in prep). The file contains a 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 km 2 . The elevation data were obtained from ArcticDEM (Porter et al., 2018) and IBCSO (Arndt et al., 2013). Arndt, J. E., Schenke, H. W., Jakobsson, M., Nitsche, F.
