Permafrost signature dataset

Dataset for the comparison between permafrost and non permafrost meandering rivers extracted with PyRIS from Landsat imagery. The dataset is split in two folders for permafrost and non permafrost river, with a subfolder for each rivers. In the rivers subfolders there is an axis folder, containing all the axis files extracted from the river masks, and there can be a migration folder, with all the data for the axis migration evaluation, where this was possible. All the files are in the '.npy' format produced and read by the Python package Numpy and the structure of the files is described in the PyRIS manual, at https://doi.org/10.5281/zenodo.10837156.
