%X 1. The data includes two vector layers: (1) permafrost layer and (2) permafrost layer_ (3) thickness of frozen soil (4) conditions of frozen soil formation (5) image correction2. The permafrost distribution map includes the following fields: area, perimeter and frozen_ ,FROZEN_ ID:POLY_ ,POLY_ ,RINGS_ OK,RINGS_ NOK, a, permafrost: frozen_ SOI, temperature. Permafrost and frozen_ SOI is the Chinese and English expression of frozen soil type. 3.
