Description

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 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).
