Periglacial landforms of Dartmoor: an automated mapping approach to characterizing cold climate geomorphology

A systematic mapping approach characterizes Dartmoor periglacial landform signatures using the geomorphology of nine summit areas displaying well developed tor and blockfield landforms. This combines manual vectorisation with automatic classification surface boulder identification, spectral to reveal patterns distribution. Tors were classified a three-fold scheme: T0 - summits no tors; T1 castellated high relief T2 subdued or low tors. Clitter (blockfield blockstream) features identified by automated include lobes stripes boulder-fronted terraces, arranged according distance downslope from parent zonation landforms is proposed as landsystem signature for exposed permafrost processes significant time during Quaternary. It represents process-form regime in which cold climate processes, acting on partially deeply weathered pneumatolysised granite, produce tors, cryoplanation benches autochthonous (clitter), creep develops that elongate evolve allochthonous blockslopes terraces. demonstrates can be applied upland rapidly systematically compile quantifiable assemblages.
