Landscape and vegetation photos and ground truthing data collected on North Core Banks, NC in October 2022

These data map in high detail surficial cross-sections of North Core Banks, a barrier island in Cape Lookout National Seashore, NC, in October 2022. U.S. Geological Survey field efforts are part of an interagency agreement with the National Park Service to monitor the recovery of the island from Hurricanes Florence (2018) and Dorian (2019). Three sites of outwash, overwash, and pond formation were targeted for extensive vegetation ground-truthing, sediment samples, bathymetric mapping with a remote ...

Lidar and photogrammetry point clouds with supporting imagery and GPS information collected during UAS operations at Great Sippewissett Marsh, Cape Cod, Massachusetts in November 2022

These lidar point clouds and images cover, in high detail, the terrain at Great Sippewissett Marsh, Cape Cod, MA on November 2nd, 2022. USGS researchers tested different sensors that collected lidar and images for photogrammetry point cloud data using Uncrewed Aerial Systems (UAS) to look at differences in coverage and elevation accuracy. The lidar data were acquired with a YellowScan Mapper lidar scanner, which consists of the Livox Horizon scanner and Applanix 15 inertial measurement unit; and a ...
