Lidar point clouds (LPC), elevation models, GPS data, image mosaics, vegetation survey, and aerial images from natural color (RGB) and multispectral cameras collected during UAS operations at Lower Darby Creek, Darby Township, Pennsylvania, August 2025
The U.S. Geological Survey deployed small uncrewed aircraft systems (sUAS) to collect aerial remote sensing data across sites within the Lower Darby Creek Superfund Site ~5 miles outside of Philadelphia, PA in March and August of 2025. March datasets include aerial images from natural color (RGB) and raw lidar of the Clearview Landfill superfund site. August datasets include aerial images from natural color (RGB), multispectral sensors, and raw lidar over the Clearview Landfill. These datasets were processed to produce high resolution digital elevation models (DEM), image mosaics, and a lidar point cloud (LPC). Black and white cross-coded ground control points (GCPs) were surveyed using Real Time Kinematic (RTK) GPS and RTK-GPS enabled AeroPoints to georeference the model and orthomosaics during post-processing. The elevation and imagery products were produced to help partners at the Environmental Protection Agency (EPA) acquire accurate elevation data for target sites during the winter "leaf-off" period (March) and monitor changes in vegetation cover during peak growing season (August) building a baseline conditions dataset starting in August 2023. Future data collections are planned to support long-term monitoring of landscape change resulting from remediation efforts and potential storm impacts.
