This page contains links to the digital elevation models and orthoimages 10-11, one month post-Hurricane Dorian. See main landing page for additional dates and information.
Aerial imagery acquired using a fixed wing aircraft fitted with Post-Processing Kinematic (PPK) GPS, was processed using Structure-from-Motion (SfM) photogrammetry techniques to produce high-resolution three-dimensional (3D) point clouds, orthomosaic images, and digital elevation models (DEMs). This dataset, produced by the U.S. Geological Survey (USGS) MD-DE-DC Water Science Center, consists of point clouds generated from the survey of four National Wildlife Refuges in New Jersey and Delaware in order to observe annual changes. Structure-from-Motion software, Agisoft Metashape, was used to perform processing on low-altitude digital aerial imagery acquired by a contractor utilizing a fixed wing aircraft. The aircraft...

This data release presents structure-from-motion (SfM) products derived from aerial imagery collected along the North Carolina coast in response to storm events and the recovery process. U.S. Geological Survey (USGS) researchers use the aerial imagery and products to assess future coastal vulnerability, nesting habitats for wildlife, and provide data for hurricane impact models. This research is part of the Remote Sensing Coastal Change Project. Products include digital elevation models and orthorectified imagery (RGB-averaged products) created from aerial imagery surveys with precise Global Navigation Satellite System (GNSS) navigation data flown in a piloted fixed-wing aircraft. The products span the coast over...

Remote-sensing technologies—such as video imagery, aerial photography, satellite imagery, structure-from-motion (SfM) photogrammetry, and lidar (laser-based surveying)— can be used to measure change along U.S. coastlines. Quantifying coastal change is essential for calculating trends in erosion and accretion, evaluating processes that shape coastal landscapes, and predicting how the coast will respond to future natural disasters (e.g. hurricanes, landslides, wildfires) and longer term climate trends such (e.g. sea-level rise, ecosystem change, coral bleaching), all critical for U.S. coastal communities. Rapid developments have occurred in remote-sensing technologies during the 21st century. With collaborators...
