PANGAEA, https://doi.org/10.1594/PANGAEA.961804

The site is situated south of Obergurgl (Ötztal Alps, Austria) on the orographic left side of the Gurgler Ache River. The local field name of the site is "auf der Nase". It contains a rock fall formation consisting of a distinctive headwall and a debris deposit in its lower section, which were meticulously monitored using a Terrestrial Laser Scanner (TLS). The results of these scans strongly indicate a potential instability of the slope. In 2022, a comprehensive TLS survey was carried out, utilizing seven scan positions and employing the advanced Riegl VZ-2000i scanner. Further data sets from 2015 and 2019 are available. This data set has been acquired at the 4th edition of the Sensing Mountains 2022 - Innsbruck Summer School of Alpine Research – Close-range Sensing Techniques in Alpine Terrain.
