Earth Surface Processes and Landforms, Volume 51, Issue 4, April 2026.This study investigates coastal cliff dynamics at Demons Bluff, a 1.5 km stretch of soft Eocene–Oligocene marine sediments along the high‐energy southern coastline of Victoria, Australia (38.405°S, 144.204°E). Using a four‐year bi‐monthly time series of UAV‐derived Structure‐from‐Motion (SfM) point clouds (n = 29), we quantify spatial and temporal ...

Mitigating ground effect on mini quadcopters with model reference adaptive control [PDF]
, 2019 Mitigating ground effect becomes a big challenge for autonomous aerial vehicles when they are flying in close proximity to the ground. This paper aims to develop a precise model of ground effect on mini quadcopters, provide an advanced control algorithm ...

UAVs unveil the role of small scale vegetation structure on wader nest survival
Remote Sensing in Ecology and Conservation, Volume 12, Issue 2, Page 211-225, April 2026.In this study, we combine high‐resolution vegetation structural metrics derived from unmanned aerial vehicle (UAV) imagery with on‐field wader nest survival monitoring. We show that the immediate vegetation height and heterogeneity within a 2‐meter buffer surrounding the clutch of the recorded ground‐nesting wader species positively influenced its ...

Tectonics, Volume 45, Issue 4, April 2026.Abstract The Northern Aegean region preserves a complex deformation pattern shaped by Miocene extension driven by retreat of the Hellenic subduction system, later overprinted by Plio–Pleistocene transtension linked to the westward propagation of the North Anatolian Fault (NAF). Although numerous structural, geophysical and geochronological studies have

High resolution spatial variability in spring snowmelt for an Arctic shrub-tundra watershed [PDF]
, 2019 Arctic tundra environments are characterized by spatially heterogeneous end-of-winter snow cover because of high winds that erode, transport and deposit snow over the winter.

APMIS, Volume 134, Issue 4, April 2026.ABSTRACT The accurate documentation of bodies, injuries, death scenes, accidents, and crime scenes is fundamental to forensic investigations. Traditional two‐dimensional (2D) photography and written reports have inherent limitations in representing complex spatial relationships.

Accuracy analysis of direct georeferenced UAV images utilising low-cost navigation sensors [PDF]
, 2014 Unmanned aerial vehicles (UAVs), also known as unmanned airborne systems (UAS) or remotely piloted airborne systems (RPAS), are an established platform for close range airborne photogrammetry. Compared to manned platforms, the acquisition of local remote
