Researcher prepares a wingtra lidar flight

Jennifer Cramer is preparing a wingtra lidar flight at the Darby Creek landfill Superfund site (Philadelphia skyline is visible on the horizon) on March 27, 2025.  sUAS, also known as a drone, is being used to model morphological changes in the tidal creek and adjacent landfill with lidar sensors, potential contaminated groundwater seeps are identified using thermal sensors, and identification of surrounding vegetation is modeled using sUAS mounted multispectral sensors.
