Digital terrain model (DTM) generation is essential to recreating terrain morphology once the
external elements are removed. Traditional survey methods are still used to collect accurate …

Riparian zones are dynamic ecosystems that form at the interface between the aquatic and
terrestrial components of a landscape. They are shaped by complex interactions between …

Unmanned Aerial Vehicles (UAVs) have revolutionised the availability of high resolution
topographic data in many disciplines due to their relatively low-cost and ease of deployment …

Image collection strategies and ground control points (GCPs) are of particular importance for
uncrewed aerial vehicle combined with Structure‐from‐Motion (UAV–SfM) photogrammetry …

The quantification of rock glacier dynamics has gained increasing importance in recent
years. In this study, the spatial and temporal flow patterns of perennially frozen debris in the …

Data on grain sizes of pebbles in gravel-bed rivers are of key importance for the
understanding of river systems. To gather these data efficiently, low-cost UAV (uncrewed …

Existing reinforced concrete (RC) bridges that were designed in the decades between 1950
and 1990 exhibit inadequate structural safety with reference to both traffic loads and hazard …

The fully automated Structure-from-Motion approach for develo** digital elevation models
and orthomosaics has been known and used in photogrammetry for at least 15 years. Years …

Accurately assessing landform evolution and quantifying rapid environmental changes are
gaining importance in the context of monitoring techniques in alpine environments. In the …

Recently, multirotor UAVs have been widely used in high-precision terrain map**,
