Digital Elevation Model (DEM) at 50 m resolution for the Everglades Depth Estimation Network (EDEN)
Since its inception, the Everglades Depth Estimation Network (EDEN) has used the High Accuracy Elevation Dataset (HAED) digital elevation model (DEM) to provide scientists and managers with continuous water depth surfaces, derived from interpolated water stage, on a 400 X 400 meter grid. A new, high resolution LiDAR-based DEM is available through a collaboration between Everglades National Park (ENP) and the U.S. Geological Survey (USGS) 3D Elevation Program (3DEP). This new DEM covers the southern part of the EDEN extent, including a large area of ENP and a portion of southeast Big Cypress National Preserve. It is provided at a resolution of 0.5 meters but contains data voids in surface water areas where the LiDAR was unable to provide adequate return (which can be caused by submerged vegetation or high turbidity). We have used multiple methods to fill these data voids and create a continuous high-resolution product for scientists, managers, and other EDEN users in the Greater Everglades. The DEM provided here was aggregated to a 50 m resolution to maintain an easily downloadable file size.
