Integrated GNSS Attitude Determination and Positioning for Direct Geo-Referencing

open access: yesSensors, 2014
Direct geo-referencing is an efficient methodology for the fast acquisition of 3D spatial data. It requires the fusion of spatial data acquisition sensors with navigation sensors, such as Global Navigation Satellite System (GNSS) receivers.

Fire Detection with UAV-Based Lidar Using Direct Georeferencing Approach

open access: yes, 2021
Wildfires have been on the rise not only in California but also in a lot of major cities around the world. Thanks to the advances in LiDAR technology, especially UAV-based LiDAR, the more traditionally ground-based methods of fire detection can hopefully

Rhododendron diversity patterns provide new insights for conserving China's montane flora

open access: yesJournal of Integrative Plant Biology, EarlyView.
Integrating distribution, phylogenetic, and functional trait data for 603 Rhododendron species in China identified significant conservation hotspots of multidimensional diversity, particularly in the Hengduan Mountains. Climate seasonality and topographic heterogeneity jointly influenced these patterns; however, notable conservation gaps remained ...

Modeling of the geographical distribution of two forest‐forming fucoids in the Strait–Alboran demarcation (southern Iberian Peninsula): Implications for conservation and restoration

open access: yesJournal of Phycology, EarlyView.
Abstract Marine forests formed by canopy‐forming brown algae of the former Cystoseira complex are key habitat‐forming components of Mediterranean coastal ecosystems, supporting biodiversity and multiple ecosystem functions. However, many populations have declined in recent decades due to increasing anthropogenic pressures and climate change, raising ...

Multiple ortho‐mosaicking software pipelines produce comparable imagery‐derived wheat phenotypes

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Unmanned aerial systems (UAS) equipped with multispectral and RGB sensors offer valuable data for monitoring crop health and assessing disease severity. However, the wide range of available photogrammetric software complicates software selection for high‐throughput plant phenotyping.

UAV‐based RGB and multispectral vegetation indices as alternatives to light box‐derived dark green color index for turfgrass color assessment

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Traditionally, turfgrass color has been assessed through visual ratings or light box‐based digital image analysis, methods that are either subjective or labor‐intensive. In this study, we evaluated the potential of unmanned aerial vehicle (UAV)‐based multispectral and red‐green‐blue (RGB) imagery as a high‐throughput alternative for capturing ...

Drone‐based phenotyping of maize for multiple disease resistance and yield in breeding field trials

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Improving selection for multiple disease resistance (MDR) and yield in maize (Zea mays L.) requires high‐throughput, objective phenotyping tools, particularly under field conditions where several foliar diseases co‐occur. We evaluated drone‐based multispectral vegetation indices (VIs) for predicting resistance to northern leaf blight (NLB ...

Pixel‐level supervision resolves overlap: Benchmarking YOLOv12 segmentation for accurate multi‐cluster dry bean stand counting from time series unoccupied aerial systems imagery

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract An agronomic trait such as stand count is important for cultivar development and crop management practices. Manually counting the number of plants is time consuming, labor‐intensive, and prone to error. The use of unoccupied aerial systems (UAS)‐collected red, green, blue (RGB) imagery in conjunction with advanced deep learning and image ...
