Estimation of the Block Adjustment Error in UAV Photogrammetric Flights in Flat Areas
Remote Sensing, 2022 UAV-DAP (unmanned aerial vehicle-digital aerial photogrammetry) has become one of the most widely used geomatics techniques in the last decade due to its low cost and capacity to generate high-density point clouds, thus demonstrating its great potential ...

Methodology for Determining Gully Widths in Multi-Temporal Studies in Olive Groves of Southern Spain
Land, 2023 This study describes a new methodology for estimating gully widths based on their digitized borders. The procedure adapts a previous method developed to determine the mean displacement between two 3D linestrings, considering them continuously, which ...

Hyperspectral outcrop models for palaeoseismic studies
The Photogrammetric Record, Volume 34, Issue 168, Page 385-407, December 2019., 2019 To overcome the limitations of the traditional study of palaeoseismic trenches, a new workflow is presented that integrates infrared hyperspectral and photogrammetric data. This method was applied on two palaeoseismic trenches excavated across a post‐glacial fault scarp in northern Finnish Lapland.

PicoCam: High‐resolution 3D imaging of live animals and preserved specimens
Methods in Ecology and Evolution, Volume 15, Issue 11, Page 1980-1989, November 2024.Abstract The PicoCam system is a multi‐camera photogrammetry rig used for generating high‐resolution 3D models of animals in the field, or preserved specimens in laboratory or museum settings. The digital measurement of 3D models is increasingly useful for studying body shape. However, methods that capture sub‐millimetric detail often do so at the cost

The fireball of November 24, 1970, as the most probable source of the Ischgl meteorite
Meteoritics &Planetary Science, Volume 59, Issue 7, Page 1658-1691, July 2024.Abstract The discovery of the Ischgl meteorite unfolded in a captivating manner. In June 1976, a pristine meteorite stone weighing approximately 1 kg, fully covered with a fresh black fusion crust, was collected on a mountain road in the high‐altitude Alpine environment.
