Time Series of Aerial Photogrammetry Data and Products of the Delaware Atlantic Coast

This data release presents a time series of aerial imagery and derived structure-from-motion (SfM) products collected along the Delaware Atlantic coast with a piloted fixed-wing aircraft. U.S. Geological Survey (USGS) researchers use the aerial imagery and products to assess topographic and landscape change, evaluate nesting habitats for wildlife, and for understanding coastal vulnerability and response to disturbance events. Products include three-dimensional (3D) point clouds and digital elevation models, and orthomosaic images (RGB-averaged products) created from aerial imagery surveys with precise Global Navigation Satellite System (GNSS) data. The products span the coast over both highly developed towns and natural areas, including Cape Henlopen State Park and Delaware Seashore State Park. The area covered extends along the entire Atlantic coast of Delaware, from Cape Henlopen to the Delaware-Maryland border. Products are provided separately for each survey and additional products will be published as more data are collected and processed. This work was supported by the U.S. Fish and Wildlife Service. �
