Major Topical systems leave significant impacts on the topography and vegetation cover of the barrier islands that they pass through. The impacts associated with these events provides valuable data about the response and recovery mechanisms of barrier islands in coastal environments. The present research is aiming to monitor, in detail, the impacts of Hurricane Florence on Masonboro Island, the longest undisturbed barrier island in southern North Carolina. Different remote sensing based, geospatial technologies are being incorporated into this study to provide a broad range of data for analysis of impact and change detection of the vegetation and elevation of the island as they recover over time. Integrating Unmanned Aerial Vehicle (UAV data, using eBee drone system) and very high-resolution satellite images (using WV-2 and WV-4 sensors data) facilitated the capturing of pre-storm conditions and the post-storm effects on the island. We hope the fusion of the UAV and RTK derived true-color orthomosaic imagery, Digital Surface Model (DSM) and satellite multispectral data enable the detection of major elevation and vegetation cover changes throughout the island. Such pre-conditions and post-storm changes can provide a detailed example of the effects of tropical systems on barrier island environments along the Coastlines in the region.
