Abstract

The AA. employed an integrated approach that combined remote sensing techniques with field measurements to predict the presence/absence of near-surface permafrost in a section of the Alaska Highway corridor. They investigated the correlative relationships among vegetation type, topography, moss thickness, tussock condition and near-surface permafrost in the study area. The statistical relationships between the surface variables (vegetation, aspect and elevation classes) and permafrost were used within a spatial model to estimate the probability of permafrost presence at any given location (or pixel) in the study area. Comparison of their probabilistic permafrost map with an independently produced photo-interpreted permafrost map showed 75% agreement for the continuously frozen class and very close agreement for the discontinuously frozen class
