Previous studies have shown that underground natural gas storage (UGS) in California has served a critical role in meeting energy demands in California, and there is no immediate alternative. Therefore, it is important to ensure the safety of UGS infrastructure, especially considering that many of the UGS sites are using a combination of new and ol...
Spatio-temporal mapping of leaf area index in rice: spectral indices and multi-scale texture comparison derived from dif...
Published in Frontiers in Plant Science
Introduction Monitoring the leaf area index (LAI), which is directly related to the growth status of rice, helps to optimize and meet the crop’s fertilizer requirements for achieving high quality, high yield, and environmental sustainability. The remote sensing technology of the unmanned aerial vehicle (UAV) has great potential in precision monitor...

How low can you go? Exploring impact of drones on haul out behaviour of harbour - and grey seals
Published in Frontiers in Marine Science
Introduction Drones, or Unmanned Aerial Vehicles (UAVs), have emerged as valuable tools for wildlife monitoring, offering potentially non-intrusive observations in challenging terrains like marine ecosystems. Despite their potential, widespread use is impeded by regulatory constraints, especially in protected areas. Methods This study aims to asses...
Reducing soil and leaf shadow interference in UAV imagery for cotton nitrogen monitoring
Published in Frontiers in Plant Science
Introduction Individual leaves in the image are partly veiled by other leaves, which create shadows on another leaf. To eliminate the interference of soil and leaf shadows on cotton spectra and create reliable monitoring of cotton nitrogen content, one classification method to unmanned aerial vehicle (UAV) image pixels is proposed. Methods In this ...
Comparative analyses for determining shallow water bathymetry potential of multispectral UAVs: case study in Tavşan Isla...
Published in Frontiers in Marine Science
Recently, the use of unmanned aerial vehicles (UAVs) in bathymetric applications has become very popular due to the rapid and periodic acquisition of high spatial resolution data that provide detailed modeling of shallow water body depths and obtaining geospatial information. In UAV-based bathymetry, the sensor characteristics, imaging geometries, ...
Hybrid algorithms in path planning for autonomous navigation of unmanned aerial vehicle: a comprehensive review
Published in Measurement Science and Technology
Path planning for unmanned aerial vehicle (UAV) is the process of determining the path that travels through each location of interest within a particular area. There are numerous algorithms proposed and described in the publications to address UAV path planning problems. However, in order to handle the complex and dynamic environment with different...
