Permafrost creep and rock glacier dynamics
Wilfried Haeberli,Bernard Hallet,Lukas U. Arenson,Roger Elconin,Ole Humlum,Andreas Kääb,Viktor Kaufmann,Branko Ladanyi,Norikazu Matsuoka,Sarah M. Springman,Daniel Vonder Mühll +10 more
TL;DR: In this article, a review paper examines thermal conditions (active layer and permafrost), internal composition (rock and ice components), kinematics and rheology of creeping perennially frozen slopes in cold mountain areas.
Quantitative analysis of rock glacier creep by means of digital photogrammetry using multi-temporal aerial photographs: two case studies in the Austrian Alps
TL;DR: In this article, the authors present a special method of measuring surface deformation and flow velocity of creeping rock glaciers based on digital photogrammetry, which is not carried out in the space of the original photos but in quasi-orthophotos derived from the use of rough and preliminary digital terrain models.
Journal ArticleDOI
Estimation of rock glacier surface deformation using SAR interferometry data
L.W. Kenyi,Viktor Kaufmann +1 more
TL;DR: The spatial distribution of the surface deformation in the D-InSAR displacement map is smooth and supports the idea that ice is the stress-transferring medium in rock glaciers.
Journal Article
Towards fully automatic photogrammetric reconstruction using digital images taken from uavs
TL;DR: This paper shows that an unmanned aerial vehicle equipped with digital cameras can provide valuable visual information about the Earth’s surface rapidly and at low cost from nearly any viewpoint and demonstrates an end-to-end workflow to process a sizeable block of such imagery in a fully automated manner.
