An overview geocryological map (1:1,000,000 scale) for an area of 136 700 km2 covering a significant part of the Bolshezemel’skaya Tundra was compiled on the basis of large-scale field permafrost-landscape surveys and interpretation of medium-resolution Landsat-7 satellite images. The method of landscape indication implemented in relation to geocryological subzones was used. Spatial variability of geocryological characteristics was analyzed at the levels of natural subzones and groups of dominant landscape units.

Keywords: geocryological mapping, remote sensing data, landscape indication, geocryological subzones.
