Multispectral classification and reflectance of glaciers: in situ data collection, satellite data algorithm development, and application in Iceland & Svalbard
… regional water resources and local biodiversity. Multispectral (visible and near-infrared) remote sensing has been used for studying GIC and their changing characteristics for several decades. Glacier surfaces can be classified into a range of facies, or zones, which can be used as proxies for …

The Development of Low-Cost Remote Sensing Technology to Monitor Invasive Alien Plant Species: The Case of Japanese Knotweed
… such as Landsat-8 and Sentinel-2 can provide multispectral and historical imagery with a spatial resolution between 10 to 30m. However, such low spatial resolution imagery cannot effectively identify and segment the several IAPS like Japanese Knotweed (Fallopia japonica) especially at the …

Phenotyping Canola (Brassica napus L.) Agronomic Traits and Estimating Seed Yield Using Unoccupied Aerial Vehicle (UAV)-based Multispectral Imagery
… such as unoccupied aerial vehicles (UAVs) and multispectral sensors, desirable phenotypic traits and seed yield can be estimated digitally. In this thesis, the main objective was to develop an efficient and non-destructive method to estimate canola flowering number, flowering layer depth, …

TACTILE AND MULTISPECTRAL BIMODAL IMAGING FOR BREAST CANCER RISK ASSESSMENT
… proposed bimodal imaging system has tactile and multispectral imaging capabilities. Tactile imaging modality characterizes tumors by esti-mating their depth, size, and stiffness, along with the Tactile Index. Multispectral imaging modality identifies breast asymmetry, texture, and inflammation …

Industrial hemp agronomic management for grain, fiber, and forage
… N content and seed yield based on UAV-based multispectral imagery. Two hemp cultivars, 'Joey' and 'Grandi', were planted and five N rates (0, 60, 120, 180, 240 kg N ha-1) were tested in Blacksburg, Virginia in 2020, 2021, 2022. Aerial image acquisition occurred at three different growth …

An Evaluation of Unmanned Aircraft Systems' Ability to Assess Stripe Rust in Large Wheat Breeding Nursies
<p>Stripe Rust (Puccinia striiformis f. sp. tritici) is a foliar disease that significantly impacts global wheat production, and resistant cultivars provide the most efficient method of control. High-throughput phenotyping using unmanned aircraft systems (UAS) offers a potentially more efficient …
