Global warming and local anthropogenic influence reduce the bearing capacity of permafrost soils, causing changes in the spatial position of pipelines and increasing the number of accidents. The proposed approach of changes in frozen soil offers: to convert the existing 4D array into a 2D view without losing information; to add new features that emphasize the seasonality and condition of permafrost; to predict missing parts of time series, and finally to re-analyze the temperature intervals of frozen soils.
