Description :
The aim of this paper is to analyse the influence of topographic and climatic variables on rock glacier distribution in the dry Andes, and to determine to what degree multispectral Landsat TM/ETM+ data can improve rock glacier detection in this arid environment. The generalised additive model (GAM) and logistic regression are used. The fusion of multisource data using modern nonlinear classification techniques is a promising step towards automatic rock glacier detection.
