Summary: This study analyzed the similarity between contour lines from topography and Remotely Piloted Aircraft (RPA), and explored the feasibility of contour planting. The results showed that there was better similarity among contour lines in areas with rugged relief, and the smallest differences in elevations were associated with the smallest Hausdorff distance. This suggests that contour planting can be performed using data obtained via RPA, as long as the quality of the Digital Elevation Models is controlled through vertical accuracy analysis.

Summary: Production agriculture has seen significant growth in the use of UAS technology to obtain real-time spectral reflectance data for the management of variability in agricultural ecosystems. This study investigated the effects of payload capacity, spray height, and ground speed on spray pattern uniformity and droplet spectra characteristics of four commercially available RPAAS platforms. The results showed that all tested platforms produced acceptable spray patterns, with increasing payload capacity resulting in a larger effective swath.

Summary: It is crucial to accurately and effectively obtain the spatial geometric characteristics of the structural surfaces of the rock mass for stability analysis of a rock slope. In this study, unmanned aerial vehicle digital photogrammetry (UAV-DP) technology was used for geological survey and stability evaluation of a high-steep rock slope in an iron ore mine to overcome the problems of inefficiency and high risk of traditional manual geological survey. The research results demonstrate the reliability of UAV-DP in geological investigation and the consistency between the stability state and failure model of the slope with field observation.

Summary: The study explores the use of Remotely Piloted Aerial Systems (RPASs) to map the spatial and temporal changes of potentially acid generating material (PAGM) across mine waste rock piles on abandoned mine lands. Supervised and unsupervised classification algorithms show benefits, with unsupervised methods requiring less user input.

Summary: The effects of climate change on food security, particularly in water-scarce areas like Murcia, have been unfavorable. This research explores the use of remote sensing to evaluate agricultural and irrigation practices and their impact on soil salinity. The study found that the Salinity Index (SI) applied to bare soil is a useful index, while other metrics such as the Normalized Difference Salinity Index (NDSI) had poor correlations. The thermal camera was effective in evaluating canopy temperature in open-air fields, but not in greenhouse conditions.

Summary: Series hybridization, distributed electric propulsion, and boundary layer ingestion are promising methods for fuel consumption reduction. However, the application of these technologies on small remotely piloted aircraft shows less significant effects due to increased propulsion system weight and reduced propeller efficiency.

Summary: Soil compaction is a significant threat to soil degradation, and this study examines the feasibility of using aerial images from a Remotely Piloted Aircraft System (RPAS) to assess soil compaction in a coffee plantation area. The results show that there were no significant differences in soil chemical analysis based on different plant heights, but there were significant statistical differences in penetration resistance, which correlates with plant height and productivity. The radiometric data was also correlated with penetration resistance, allowing for estimation of compaction data.

Summary: Uncrewed aerial vehicles are commonly used for hyperspectral imaging, but mostly in nadir imaging orientations. Oblique hyperspectral imaging is hindered by the lack of robust registration and correction protocols. In this paper, a novel correction methodology and toolbox are proposed for accurate production of hyperspectral data acquired by UAVs, without any restrictions on view angles or target geometry. The importance of these corrections is demonstrated through the first fully corrected oblique SWIR drone-survey.

Summary: Measuring glacier elevation change is crucial for various purposes, such as estimating glacier mass balance, calibrating climate models, and assessing the impact of global warming. In this study, we explored the potential of clinometry as a technique to quantify glacier elevation changes. By analyzing shadow positions in monoscopic optical images, we were able to measure a glacier thinning rate of -1.9 +/- 1.7 ma(-1) between 2017 and 2021 for the Aletsch Glacier (Switzerland), consistent with previous observations.

Summary: The coastal region of southwest Saudi Arabia contains a thick sequence of Late Oligocene basalts in the Jizan Group. These basalts lack primary permeability but are cross-cut by fractures. The area is composed of half-grabens and exhibits a highly fractured nature. This makes it suitable for the injection and mineral carbonation of carbon dioxide from industrial sources.

Summary: A dedicated procedure has been implemented to explore the behavior and define the state of activity of 279 deep-seated gravitational slope deformations (DsGSDs) in the Aosta Valley Region. The procedure involves the use of Differential Interferometry Synthetic Aperture Radar (DInSAR) techniques to detect and identify Persistent Scatterers (PSs) and assess Sentinel-1 data coverage. Spatial analysis based on cluster and outlier identification is carried out to characterize the moving phenomena and their degree of variability in deformation rates. The methodology provides a valid instrument to remotely define the state of activity of these phenomena, which are often underestimated or neglected in risk management.
