Description :
The AA. present a new modelling approach that integrates topographical, ground and remote sensing information in predictive geomorphological mapping using generalized additive modeling (GAM). The results indicate that non-sorted patterned ground is more common at lower altitudes where the ground moisture and vegetation abundance is relatively high, whereas sorted patterned ground is dominant at higher altitudes with relatively high slope angle and sparse vegetation cover. This paper confirms the potential utility of remote sensing information for modelling patterned ground distribution in subarctic landscapes.
