RPAS and GIS for landfill analysis

E3S Web of Conferences, 2018
Using remote sensing methods to capture environmental contamination is very relevant not only to Lithuania, but also to the whole of Europe. The article examines the Remotely Piloted Aircraft System (RPAS) and its components, in particular aircraft (UAV)

Intercomparison of a Regional Climate Model Ensemble for Selected European Catchments

International Journal of Climatology, EarlyView.
This study analyzes a regional climate model ensemble for water cycle and water resource research with two models. Results show that ICON generally outperforms TSMP1 simulations, mainly with 2‐m temperature and precipitation. These findings serve as a baseline evaluation that shows how key structural differences influence the model skill.

Wheat Sowing Practices in No‐Tillage Systems Modify the Microrelief and Hydrosedimentological Attributes: RPAS‐Based Photogrammetry

Land Degradation &Development, EarlyView.
ABSTRACT The microtopographic characteristics of terrain are modified by soil management and conservation practices, affecting water infiltration, storage, runoff generation, and sediment transport. However, assessing soil microtopography at representative spatial scales remains challenging and time‐consuming.

Remote Pilot Aircraft System (RPAS): just Culture, Human Factors and Learnt Lessons

Chemical Engineering Transactions, 2016
Significant efforts invested in unmanned air vehicle (UAV) technology lead to a wide variety of new applications such as aero-photography and surveillance (Kontogiannis et al., 2013) and the operation of remotely piloted aircraft system (RPAS) undoubtedly has a great impact on the aviation industry and on the industrial applications.

Climate‐Driven Mangrove Dieback and Recovery: A Case Study in Albert and Leichhardt Rivers, Australia

Remote Sensing in Ecology and Conservation, EarlyView.
Cycles of dieback and recovery drove mangrove forest dynamics at the Albert and Leichhardt Rivers (Gulf of Carpentaria, Queensland, Australia) over 36 years (1987–2023). Landward margins were the most affected by reduced tidal inundation when the alignment of low lunar declination suppressed tidal range and extreme El Niño phases lowered mean sea level.

Measurement of surface velocity in open channels using a lightweight remotely piloted aircraft system

Geomatics, Natural Hazards & Risk, 2017
In this paper, a low-cost remotely piloted aircraft system (RPAS) technique is proposed for measurement of the surface velocity in rivers or channels with low surface velocity and small discharge.

Use of a remotely piloted aircraft system for hazard assessment in a rocky mining area (Lucca, Italy) [PDF]

Natural Hazards and Earth System Sciences, 2018
The use of remote sensing techniques is now common practice in different working environments, including engineering geology. Moreover, in recent years the development of structure from motion (SfM) methods, together with rapid technological ...

Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain

Wildlife Biology, EarlyView.
Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

Remotely Piloted Aircraft Systems as a Rhinoceros Anti-Poaching Tool in Africa

PLoS ONE, 2014
Over the last years there has been a massive increase in rhinoceros poaching incidents, with more than two individuals killed per day in South Africa in the first months of 2013. Immediate actions are needed to preserve current populations and the agents involved in their protection are demanding new technologies to increase their efficiency in the ...
