    <descript>
      <abstract>Small Uncrewed Aircraft Systems (sUAS) were used to collect aerial remote sensing data over Town Neck Beach, a highly trafficked local beach in Sandwich Massachusetts with parking lot, boardwalk, and state maintained sand and vegetation placement. USGS personnel collected natural (RGB) color images, LiDAR, and ground control points starting in December 2023 to support multiple science projects. These data were processed to produce a high resolution point cloud, digital elevation models (surface and terrain), and a natural-color orthomosaic. Data support observations of coastal change.</abstract>
      <purpose>The elevation and imagery products were produced to help the sites conservation partnership evaluate the baseline conditions of the site, with future data collections planned to monitor landscape change from remediation efforts and potential storm impacts.</purpose>
