flexFitR and exploreHTP: Open‐source software to enable nonlinear modeling of plant growth from remote‐sensing imagery

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract In this study, we introduce two complementary R packages: exploreHTP and flexFitR. exploreHTP is a Shiny‐based graphical interface for extracting plot‐level data from remote‐sensing imagery, while flexFitR provides tools for nonlinear model‐fitting and trait derivation from time series.

Unit 29 - Discrete Georeferencing [PDF]

open access: yes, 1990
This unit concludes the module on coordinate systems and geocoding. Several important practical issues are raised here that will be important particularly for those who will be working with economic and demographic databases.

An In-Depth UAS-PPK Georeferencing Analysis at Different Flight Heights for an Urban Area

open access: yesIEEE Access
Acquiring UAS images in urban environments presents a significant importance for various applications but presents challenges, particularly with flight missions and the reliability of the Global Navigation Satellite System (GNSS) signal.

Phenomic prediction of wheat yield and grain quality using multispectral, hyperspectral, and thermal imagery

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Grain quality in durum wheat (Triticum turgidum L. subsp. durum (Desf.) Husn.) remains a major challenge for plant breeders because grain yield and grain protein concentration often show a trade‐off, and both are influenced by grain nitrogen concentration.

Exploring the Potential of Unmanned Aerial System‐Based Topographic Indices Maps to Evaluate Storm Drain Positioning

open access: yesJournal of Flood Risk Management, Volume 19, Issue 4, December 2026.
ABSTRACT Urbanisation, climate uncertainty, and limited city budgets have heightened the need for efficient urban drainage management. While advanced hydrodynamic models assess the performance of drainage networks, they are computationally intensive, time‐consuming, and expensive.

Spatial variation and predictors of plant species' intrinsic climate sensitivity across the conterminous United States

open access: yesEcography, Volume 2026, Issue 11, November 2026.
Understanding how species' sensitivity to climate varies spatially across their ranges and elucidating the important causes is essential for identifying ecologically meaningful geographic units and conservation actions for biodiversity. In this study, we estimated climatic occurrence niches of vascular plants to explore the spatial variation in species'

UAV Data Collection Co-Registration: LiDAR and Photogrammetric Surveys for Coastal Monitoring

open access: yesDrones
When georeferencing is a key point of coastal monitoring, it is crucial to understand how the type of data and object characteristics can affect the result of the registration procedure, and, above all, how to assess the reconstruction accuracy. For this

A validated 3D point‐cloud analysis workflow for the creation of seagrass canopy height models

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 11, Page 3136-3156, November 2026.
Abstract Seagrasses support highly productive ecosystems in both temperate and tropical waters and provide essential ecosystem services. Despite their importance, the vertical structure of seagrasses (i.e. the canopy) remains poorly characterised at the microscale, even though it is a strong predictor of ecological processes that influence both ...
