UAV Georeferencing for High-Precision Spatial Localization of Surfacing Yangtze Finless Porpoises

open access: yesDrones
Accurate spatial localization of small, transient targets in low-texture aquatic environments remains a fundamental challenge in UAV-based remote sensing, where open-water surfaces often lack stable tie points, degrading exterior orientation estimation ...

Leukemia and Exposure to Potential Benzene Sources in Children From the Mexico City Metropolitan Area, 2010–2021: A Geospatial Analysis

open access: yesPediatric Blood &Cancer, Volume 73, Issue 9, September 2026.
ABSTRACT Background Leukemia is the most common childhood cancer in Mexico, and acute lymphoblastic leukemia (ALL) is the most frequent subtype. Exposure to high concentrations of benzene has been associated with ALL incidence, particularly in urban areas. This study evaluated the relationship between distance to benzene emission sources and the number

Direct Georeferencing with GPS in Terrestrial Laser Scanning

open access: yes, 2010
In this paper, a combined terrestrial laser scanning survey system is presented, where GPS can be used for direct georeferencing of the point clouds. The results of investigations of this system show that it is possible to achieve the coordinate accuracy of better than 1 cm in the point cloud, both in plane and height, at the object distance of up to ...

Exploring Differences in Precision Agriculture Adoption: New and Beginning Farmers, and Established Farmers

open access: yesApplied Economic Perspectives and Policy, Volume 48, Issue 4, Page 970-983, September 2026.
ABSTRACT This paper compares precision agriculture (PA) adoption between new and beginning farmers (NBFRs) and established farmers using data from a 2021 U.S. Midwest farmer survey. We focus on the human capital of two different groups of farmers in the PA adoption.

Predictive models of seed yield in intermediate wheatgrass (Thinopyrum intermedium): The added value of a time series of multispectral imagery in semiarid environments

open access: yesAgronomy Journal, Volume 118, Issue 5, September/October 2026.
Abstract Accurate estimation of seed yield in perennial grains like Thinopyrum intermedium (intermediate wheatgrass [IWG]) remains a challenge due to high interannual and spatial variability of this important trait. We evaluated the potential of before‐harvest unmanned aerial vehicle (UAV)‐derived multispectral vegetation indices to predict IWG seed ...
