This data is the distribution and general properties of frozen soil and seasonal frozen soil in the Republic of Mongolia
1. The data includes two layers: Permafrost map 1:12000000, permafrost map 1:4500, permafrost map 1:4500, permafrost map 2:4500, permafrost map 2:4500, permafrost map 1:4500, permafrost map 1:4500, permafrost map 2:4500, permafrost map 1:4500, permafrost map 1:4500, permafrost map 1:4500, permafrost map 1:4500, permafrost map 1:4500, permafrost map 1:4500, According to altitude, annual average temperature, frozen soil depth, freeze-thaw depth, seasonal frozen soil and seasonal frozen depth, it can be divided into 14 types.
3. The data includes the following layers:
cryo_ landslide.shp (point locations of cryogenic landslides)、cryo_ planation.shp (point locations of cryogenic planation)、dig_ country_ bnd.shp (digitized country boundary polygon from the 1:4,500,000 map)、dig_ lakes.shp (digitized lake polygons from the 1:4,500,000 map)、 treams.shp (digitized stream vectors from the 1:4,500,000 map)、geocryo_ regions.shp (digitized geocryological region polygons from the 1:12,000,000 map. See the attribute description below)、 geocryology.shp (digitized polygons of areas with detailed geocryological information from the 1:4,500,000 map. See the attribute description below)、 icings.shp (point locations of icings)、
per_ frost_ mound.shp (point locations of perennial frost mounds)、 solifluction.shp (point locations of solifluction)、 thermokarst.shp (point locations of thermokarst)。
