| description | <p>Active rock glaciers and landslides are dynamic landforms in high mountain environments, where their geomorphic activity can pose significant hazards, especially in densely populated regions such as the European Alps. Moreover, active rock glaciers reflect the long-term thermal state of permafrost and respond sensitively to climate change. Traditional monitoring methods, such as in situ differential Global Navigation Satellite System (GNSS) and georeferenced total station (TS) measurements, face challenges in measuring the rapid movements of these landforms due to environmental constraints and limited spatial coverage. Remote sensing techniques offer improved spatial resolution but often lack the necessary temporal resolution to capture sub-seasonal variations. In this study, we introduce a novel approach utilising monoscopic time-lapse image sequences and artificial intelligence (AI) for high-temporal-resolution velocity estimation, applied to two subsets of time-lapse datasets capturing a fast-moving landslide and rock glacier at the Grabengufer site (Swiss Alps). Specifically, we employed the Persistent Independent Particle tracker (PIPs<span class="inline-formula"><math xmlns="http://www.w3.org/1998/Math/MathML" id="M1" display="inline" overflow="scroll" dspmath="mathml"><mrow><mo>+</mo><mo>+</mo><mo>)</mo></mrow></math><span><svg:svg xmlns:svg="http://www.w3.org/2000/svg" width="21pt" height="12pt" class="svg-formula" dspmath="mathimg" md5hash="0fb12ca3541580bd383f89224af1f329"><svg:image xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="esurf-13-705-2025-ie00001.svg" width="21pt" height="12pt" src="esurf-13-705-2025-ie00001.png"/></svg:svg></span></span> model for 2D image point tracking and the image-to-geometry registration to transfer the measured 2D image points into 3D object space and further into velocity data.
