Résumé(disponible en anglais seulement)
The vegetation maps were originally prepared by the Forest Management Institute of the Canadian Forestry Service for the Environmental-Social Program of the Task Force on Northern Oil Development. They were subsequently digitized by Natural Resources Canada (Geological Survey of Canada) for use in a ground thermal modeling project. Secondary benefit of digitizing the 1974 paper maps was data preservation to a digital format easily accessible in a Geographic Information System. The data represent a broad classification of the vegetation in the Mackenzie Valley Transportation Corridor, which stretches along the Mackenzie River, Northwest Territories, from the Alberta border to the Beaufort Sea (10° of latitude). Included in the dataset are information on species composition, and canopy height and density of the forest cover. Landform modifiers are also included for areas of tundra vegetation. The vegetation was interpreted from black and white panchromatic aerial photographs taken between 1970 and 1972. Additional infrared colour photography was taken in 1971 and 1972 to cover a small portion of the area. Field checks of the maps took place at 314 sites in 1971 and 1972.
