Drone Imagery Applied to Enhance Flood Modeling
… does not exist. This paper proposes using drone imagery to compensate for the lack of other flood modeling data (i.e. streamflow measurements). Three flood models were run for Dzaleka Refugee Camp, located in Dowa, Malawi. Two of the models (the Soil and Water Assessment Tool (SWAT) and the …

Meteorological and geomorphological influence on harbor seal haul-out distribution behavior using drone imagery
… conditions affect seal haul-out site use. Using drone surveys, high-resolution elevation models and slope maps were produced for major haul-out sites. Drone surveys from 2021 to 2023 provided seal counts during key life history stages—pupping and molting—with seal identified manually or using …

Evaluation of Rotational Bale Grazing as an Alternative Winter-Hay Feeding System for Beef Cows
… was measured using ground manual samples and drone imagery. Manual samples and drone flights were conducted three times post-winter hay feeding. While the SP system exhibited the highest biomass recovery in high animal impact areas, RBG showed numerically higher biomass by the third sampling …

Identifying New Potential Breeding Pond Sites for the Dusky Gopher Frog in Southern Mississippi
… a time efficient manner. Field observations and drone imagery allowed for the examination of four potential pond sites identified within the ArcGIS software. Although one site was eliminated for failing to meet the criteria for dusky gopher frog introduction, the remaining three sites appear …

Pre- and Post-Disaster Remote Sensing with Drones for Supporting Disaster Management
Small (< 25 kg) aerial drones have expanded the remote sensing toolkit for disaster management activities, resulting in hundreds of published case studies in the past two decades. The overall goal of this doctoral research, which comprises three related studies, is to evaluate drone-based pre- and …

Diversity patterns and conservation priorities in the "Mountains of Central Asia" biodiversity hotspot
… classification, and RGB and multispectral drone imagery. The study established a baseline assessment of the country’s segetal flora and demonstrated that regional species pools and the proximity of adjacent slopes strongly shape species composition. Large lowland croplands were …

Reciprocal Transplant and Machine Learning Study of Oak Mistletoe on Three Host Oak Species in Santa Margarita, California
… trees were classified with 87% accuracy using drone imagery and 95% accuracy using open source NAIP imagery. This classification technique could be applied to the whole state of California as long as ground truth points for each species were collected. This could be extremely useful for large …

Aerial Cadastral and Flood Assessment for Disaster Risk Management in Appalachia
… to homes and other property. Using low-cost drones, 3D cadastre models can be created and combined with flood models to quantify individual building risk before, during, and after flood events. As severe flooding devastated areas nearby to Virginia Tech, the need for accurate flood risk …
