Prediction of symbiotic nitrogen fixation in common bean (Phaseolus vulgaris L.) using unmanned aerial system remote sensing

open access: yesThe Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract Common bean (Phaseolus vulgaris L.) can fix atmospheric nitrogen (N) through symbiosis with Rhizobia species. This trait is often underutilized by growers and overlooked by breeders due to the laborious and costly evaluation techniques involved.

An unsupervised classification method for inferring original case locations from low-resolution disease maps [PDF]

open access: yes, 2006
Background: Widespread availability of geographic information systems software has facilitated the use of disease mapping in academia, government and private sector. Maps that display the address of affected patients are often exchanged in public forums,

Enhancing trait measurement in forage sorghum using unoccupied aerial systems

open access: yesThe Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract Forage sorghum (Sorghum bicolor L. Moench) can be classified into several different types, ranging from sudangrass to silage sorghum. The exact type of forage sorghum is defined by basic plant characteristics (maturity, height, and tillering), the end use, and type of biomass produced.

Comparative Assessment of the Effect of Positioning Techniques and Ground Control Point Distribution Models on the Accuracy of UAV-Based Photogrammetric Production

open access: yesDrones
Unmanned aerial vehicle (UAV) systems have recently become essential for mapping, surveying, and three-dimensional (3D) modeling applications. These systems are capable of providing highly accurate products through integrated advanced technologies ...

Feature-based groupwise registration of historical aerial images to present-day ortho-photo maps

open access: yes, 2018
In this paper, we address the registration of historical WWII images to present-day ortho-photo maps for the purpose of geolocalization. Due to the challenging nature of this problem, we propose to register the images jointly as a group rather than in a ...

Empirical Evaluation and Simulation of GNSS Solutions on UAS-SfM Accuracy for Shoreline Mapping

open access: yesDrones
Uncrewed aircraft systems (UASs) and structure-from-motion/multi-view stereo (SfM/MVS) photogrammetry are efficient methods for mapping terrain at local geographic scales.

Are species occurrence data in global online repositories fit for modeling species distributions? The case of the Global Biodiversity Information Facility (GBIF). Final Report of the Task Group on GBIF Data Fitness for Use in Distribution Modelling. [PDF]

open access: yes, 2016
Primary Biodiversity Data (PBD) are defined as the basic attributes of observations or records of the occurrences of species. PBD is a fundamental concept of biodiversity informatics since it is substantial in quantity and provides the links to organize ...
