Ground Elevation Model

DEM - October 2011
(Posted December 2011)

Ground elevation data for the greater Everglades and the digital ground elevation models (DEM) derived from them form the foundation for all EDEN water depth and associated ecological/hydrologic modeling.

This DEM was produced using the version HAED_v01 of the HAED (High Accuracy Elevation Dataset). To learn more about the data collection and DEM development, see the "For More Information" panel to the left.

The ground elevation, and therefore water depth, in the Everglades can vary by centimeters or tens of centimeters within a few meters of a given location as a result of microtopographic features. In addition, ground surface elevations in the peat soils of the Everglades can drop during droughts due to compaction as the peat dries and can rise again in the wet season with re-hydration. The elevation value for each EDEN 400m by 400m grid cell is a modeled value influenced by variation in the aerial height finder data surrounding the grid cell. Users are cautioned to use the EDEN data appropriately for site-specific assessments.

Please note:

• The EDEN grid is used to grid the ground elevation DEM into 400m by 400m rectangles (“cells”) and allows for georeferenced layering with other EDEN datasets.
