    "descript": "A small Uncrewed Aircraft System (sUAS) was used to collect aerial remote sensing data over Town Neck Beach, Sandwich, Massachusetts to monitor landscape change. On June 2nd, 2025, USGS personnel collected lidar, natural (RGB) color images, GPS check points, and ground control points. These data were processed to produce a lidar point cloud, high-resolution digital surface model, and natural-color orthomosaic. These will be used to compare how the site has changed and validate the total water level data.",
