Canada's permafrost extent and ground ice abundance are mapped based on physiographic regions from the 5th Edition National Atlas. The dataset includes point data for permafrost temperature and thickness at specific sites, plus maps of mean annual ground temperatures. It was compiled by Heginbottom, Dubreuil, and Harker and published by Natural Resources Canada in 1995.
Data is provided in multiple cartographic and GIS formats (SHP, PDF, JPG, etc.), not as a single structured table. License is OGL-CA-2.0.
