Plot‐level satellite imagery can substitute for UAVs in assessing maize phenotypes across multistate field trials

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 4, Page 1011-1026, July 2025.
Maize plays a key role in agricultural profitability and food security on six continents. Successful efforts to breed higher‐yielding maize varieties depend on replicated yield trials in many environments. Capturing in‐season data can help improve and accelerate the development of regionally adapted hybrids, but collecting these data can be impractical

Habitat heterogeneity from lidar and hyperspectral data: Implications for bird guilds and restoration management of coal mines

open access: yesJournal of Applied Ecology, Volume 62, Issue 7, Page 1659-1673, July 2025.
This study underscores the need to design a mosaic of habitats with complex vertical structures, emphasising the critical role of senescent vegetation and unaltered terrain features in supporting biodiversity. Finally, it provides evidence that integrating habitat heterogeneity metrics derived from airborne remote sensing data into restoration success ...

Complete Model for Automatic Object Detection and Localisation on Aerial Images using Convolutional Neural Networks

open access: yesJournal of Communications Software and Systems, 2018
In this paper, a novel approach for an automatic object detection and localisation on aerial images is proposed. Proposed model does not use ground control points (GCPs) and consists of three major phases.

Potential and constraints of uncrewed aerial vehicle orthoimagery for rivers: A direct comparison with field measurements for mapping boulders

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 8, 30 June 2025.
Both field and drone surveys are commonly used to map river landforms. Comparing the two, we found that drones consistently underestimated boulder density and coverage by 30%, with the difference best explained by water depth. Abstract Technological advances continue to improve our ability to detect landforms and landscape changes.

Thermal Infrared Image Georeferencing using an Ensemble of Land Cover Predictions [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Precise georeferencing of remote sensing data is usually implemented in a post-processing fashion and is a crucial step for Earth observation applications such as change detection, natural hazard management, and ground target tracking. It is particularly

Morphoevolutive drivers on a rapidly‐evolving soft rocky cliff and connected shore platform system

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 8, 30 June 2025.
A multi‐source approach combining UAV surveys, optical satellite images and meteo‐marine data identifies key morphoevolutive drivers on a soft rocky cliff system. Results highlight the role of lithology and structure as primary controls, with marine and rainfall forcing acting as preparatory agents in a rapidly evolving coastal landscape.
