    "descript": "Small Uncrewed Aircraft Systems (sUAS) were used to collect aerial remote sensing data over Marsh Island, a salt marsh restoration site along New Bedford Harbor, Massachusetts. Remediation of the site will involve direct hydrological and geochemical monitoring of the system alongside the UAS remote sensing data. On July 23rd, 2025, USGS personnel collected natural (RGB) color images, multispectral images, thermal images, lidar, and ground control points. These data were processed to produce a high-resolution lidar point cloud (LPC), digital elevation models (surface and terrain), and natural color, multispectral, and thermal orthomosaics. Data collection is related to USGS Field Activity 2025-009-FA and this release only provides the UAS portion.",
