Abstract
This dataset contains shoreline polylines of Wallops and Assawoman islands, Virginia, delineated from Planet Labs satellite imagery. The dataset spans August 2016 to 2025, with monthly observations increasing to biweekly from August 2020 to September 2021 during NASA's 2020-2021 beach renourishment project on Wallops Island. The imagery resolution is 3 meters, enabling detailed and accurate shoreline delineation. The wet-dry line was traced in ArcGIS Pro to capture temporal changes in the island's coastal boundary. Shorelines were created and are stored in the WGS 1984 UTM Zone 18N coordinate system. Data is saved in an ArcGIS Pro 3.4.0 geodatabase, stored in a .zip file.
