Permafrost Characteristics of Alaska - 2008 Shapefile
This shapefile was used to generate a permafrost map of Alaska that was presented in conjunction with the Ninth International Conference on Permafrost held at the University of Alaska in 2008. The permafrost shapefile is coded with surficial geology, mean annual air temperature (MAAT), primary soil texture, permafrost extent, ground ice volume and primary thermokarst landforms.
Original surficial geology compiled from hand delineations on 1:250,000 USGS topo maps. Significant horizontal errors (1-3kms) can be found when compared to ortho corrected imagery. See process description in FGDC metadata view for full description of data compilation. Use data at a scale appropriate for general state-wide mapping or assessment.
