In my research I use spatial datasets to produce habitat maps and analyze the spatiotemporal dynamics of coastal systems. The focus of my thesis is using imagery collected by unmanned aerial systems to characterize Florida’s intertidal oyster reefs. I am using Object-Based Image Analysis to delineate reefs from surrounding habitats as well as oyster shell from surrounding substrate within an individual reef. Object-Based Image Analysis is a more robust analysis technique than traditional pixel-based methods as it divides images into meaningful objects using spectral and textural characteristics. I will use the information from the Object-Based Image Analysis in a broader seascape ecology context to study which spatial variables may contribute to a reef’s success or failure.
