    • Drone imagery for CRMS Site 3166 (DTM)

    Metadata Updated: January 7, 2026

    South Louisiana's continued land-loss due to erosion and subsidence is a constant process and demands attention though restoration and mitigation efforts. Data is needed to determine elevation and vegetation related to subsidence, climate change and saltwater intrusion. This information is critical to our partners for continued monitoring of marsh in degrading landscapes. Whether from subsidence, erosion or other factors, changing sediments are having detrimental effects on the marsh landscape. Providing imagery and digital surface models will help researchers correlate other datasets to determine factors contributing to marsh changes.
