Journal ArticleDOI
On the need for a time- and location-dependent estimation of the NDSI threshold value for reducing existing uncertainties in snow cover maps at different scales
TL;DR: In this paper, the authors use local snow cover maps derived from ground-based photography to continuously calibrate the normalized-difference snow-index (NDSI) values of Landsat satellite images at two European mountain sites of the period from 2010 to 2015.
Journal ArticleDOI
PRACTISE – Photo Rectification And ClassificaTIon SoftwarE (V.1.0)
TL;DR: The results obtained show that PRACTISE is a fast and user-friendly tool, able to derive the microscale variability of snow cover extent in high alpine terrain, but can also easily be adapted to other land surface applications.
Journal ArticleDOI
Description of current and future snow processes in a small basin in the Bavarian Alps
TL;DR: In this article, the authors used the Cold Regions Hydrological Modelling platform (CRHM) to compile a model for simulating the snow cover development within the research catchment Zugspitze (RCZ; 11.4 km2/Germany).
Journal ArticleDOI
PRACTISE – Photo Rectification And ClassificaTIon SoftwarE (V.2.1)
TL;DR: The results show that using terrestrial photography in combination with satellite imagery can lead to an objective, reproducible, and user-independent derivation of the NDSI threshold and the resulting snow cover map.
Journal ArticleDOI
Der Wert Alpiner Forschungseinzugsgebiete im Bereich der Fernerkundung, der Schneedeckenmodellierung und der lokalen Klimamodellierung
TL;DR: In this article, the authors present a fall-case study, wertvoll sind in alpiner Forschungseinzugsgebiete im Kontext optimierter Modellsetups, verbesserter Modellergebnisse und abgeleiteter Fernerkundungsprodukte aufgezeigt werden.
