Abstract Details

2018, Master of Science (MS), Ohio University, Geography (Arts and Sciences).
This project acquired high-resolution, RGB images of a deciduous forest in Athens, Ohio from an unmanned aerial vehicle over the course of a year. With UAVs, greater temporal and spatial scales exist today than what were available in the recent past with the full capabilities of these images yet to be fully assessed. The goal of the project was to follow the different phenology patterns of various deciduous trees to accurately map the project site while formulating a reproducible methodology for future work. Acquiring mosaics for 29 dates in 2017, a supervised Maximum Likelihood Classification scheme was employed to classify various species using 15 of the mosaics. Simultaneously, spectral profiles were built for 16 common species at the site using 25 of the mosaics. A community level map displaying three main groups was produced for the study site along with a phenology calendar which highlights key dates for identifying various species. The results of this project show that many species have a high amount of overlap in their spectral signals following phenology, making differentiation of individual species difficult when employing a pixel-based approach alone.
