Automated classification of debris-covered glaciers combining optical, SAR and topographic data in an object-based environment
Robson, Benjamin Aubrey; Nuth, Christopher; Dahl, Svein Olaf; Hölbling, Daniel; Strozzi, Tazio; Nielsen, Pål Ringkjøb (Peer reviewed; Journal article, 2015-12)Satellite imagery is increasingly used to monitor glacier area changes and create glacier inventories. Robust and efficient pixel-based band ratios have proven to be accurate for automatically delineating clean glacier ... -
Automated detection of rock glaciers using deep learning and object-based image analysis
Robson, Benjamin Aubrey; Bolch, Tobias; MacDonell, Shelley; Hölbling, Daniel; Rastner, Philipp; Schaffer, Nicole (Journal article; Peer reviewed, 2020)Rock glaciers are an important component of the cryosphere and are one of the most visible manifestations of permafrost. While the significance of rock glacier contribution to streamflow remains uncertain, the contribution ... -
Decadal Scale Changes in Glacier Area in the Hohe Tauern National Park (Austria) Determined by Object-Based Image Analysis
Robson, Benjamin Aubrey; Hölbling, Daniel; Nuth, Christopher; Strozzi, Tazio; Dahl, Svein Olaf (Peer reviewed; Journal article, 2016-01-15)In this paper, we semi-automatically classify clean and debris-covered ice for 145 glaciers within Hohe Tauern National Park in the Austrian Alps for the years 1985, 2003, and 2013. We also map the end-summer transient ... -
Estimating the volume of the 1978 Rissa quick clay landslide in Central Norway using historical aerial imagery
Robson, Benjamin Aubrey; Hölbling, Daniel; Nielsen, Pål Ringkjøb; Koller, Max (Journal article; Peer reviewed, 2022)Quick clay is found across Scandinavia and is especially prominent in south-eastern and central Norway. Quick clay is prone to failure and can cause landslides with high velocities and large run-outs. The 1978 Rissa landslide ...
