Journal ArticleDOI
Unmanned aerial vehicle-based remote sensing for rangeland assessment, monitoring, and management.
Albert Rango,Andrea S. Laliberte,Jeffrey E. Herrick,Craig Winters,Kris M. Havstad,Caiti Steele,Dawn M. Browning +6 more
TL;DR: The ability to depict the land surface commensurate with field data perspectives across broader spatial extents is unrivaled and is directly applicable to operational agency needs for measuring and monitoring.
Journal ArticleDOI
Acquisition, orthorectification, and object-based classification of unmanned aerial vehicle (UAV) imagery for rangeland monitoring.
TL;DR: In this article, the authors examined the potential of using a small UAV for rangeland inventory, assessment and monitoring, and developed a semiautomated orthorectification procedure suitable for handling large numbers of small-footprint UAV images.
Journal ArticleDOI
UAS remote sensing missions for rangeland applications
TL;DR: In this article, the authors describe a proven workflow for UAV-based remote sensing, and discuss geometric errors of image mosaics and classification accuracies at different levels of detail.
Journal ArticleDOI
Characterising the Spatial and Temporal Activities of Free-Ranging Cows from GPS Data
Dean M. Anderson,Craig Winters,Richard E. Estell,Ed L. Fredrickson,Marek Doniec,Carrick Detweiler,Daniela Rus,Darren K. James,Barbara Nolen +8 more
TL;DR: Overall, travel by cows increased post-weaning with subtle within-day behavioural changes, suggesting the biological importance of spatio-temporal behaviour to optimise cattle and landscape management goals.
A procedure for orthorectification of sub-decimeter resolution imagery obtained with an unmanned aerial vehicle (uav)
TL;DR: In this article, an automated procedure was developed to improve the accuracy of the exterior orientation by matching the UAV images to an orthorectified reference image. But the accuracy was limited due to the difficulty in locating ground control points and in automatic generation of tie points, and relatively large errors in exterior orientation.
