Everglades Depth Estimation Network (EDEN) Water Surfaces Data

Spatially continuous interpolation of water surface across the greater Everglades is generated for daily mean values of the water level gages for the EDEN network beginning January 1, 2000. Surfaces are recorded as elevations in centimeters relative to the North American Vertical Datum of 1988 (NAVD 88). These surfaces are served on the web as GIS data layers.

Spatially explicit hydrologic information can be critical in understanding and predicting changes in biotic communities in wetland ecosystems. Repeated field measurements, the traditional method of collecting water surface information, is labor intensive and doesn't produce spatially continuous data across large areas. For this reason the EDEN project was started to collect data from over 200 real time stage monitoring gages that automatically record and radio-transmit data. The project integrates existing and new telemetered water level gages into a single network. Combined with a high resolution ground elevation model it generates a daily continuous water surface and water depth for the freshwater greater Everglades.
