Description
Summary:Sheets 7 and 11 were scanned from the Russian version of "Geocryological map of Russia and neighboring republics, 1:2,500,000 scale" (Yershov et al. 1991). The English Language Edition of the Geocryological Map of Russia and Neighboring Republics - translations and commentary" (Williams and Warren, 2003) were used to translate the map legends. A subset of the map was manually vectorized in ArcGIS (digitized extent: WGS84, upper left corner: lat 65, long 117.55, lower right corner: lat 61.05, long 131.05). Selected layers were: Permafrost thickness (in meter), Volumetric Ice content (volume fraction), Distribution of cryogenic phenomena (ice wedges, frost heave mounds, thermokarst lakes and depressions, massive ice beds), Permafrost extent/coverage d=discontinuous, c=continuous, pc= Predominantly continuous permafrost, Surface geology (quaternary deposit), mean annual temperature (in °C at the depth of zero annual amplitude).ESRI shapefiles were stored as GCS WGS84 with an associated layer file for each theme.
