Abstract

The extent of near-surface permafrost, or perennially frozen ground within 3 m of the surface, was estimated for the Mackenzie River delta by determining its association with riparian vegetation communities in the field, and by subsequently mapping these vegetation communities using SPOT-5 data and the supervised maximum-likelihood classification technique. Multispectral SPOT-5 data were classified with overall accuracies greater than 80 per cent. In contrast to the most recent "Permafrost Map of Canada", these results indicate that the Mackenzie Delta is part of the continuous permafrost zone
