Everglades Depth Estimation Network (EDEN) Water Surfaces DataEntry ID: USGS_SOFIA_eden_water_surfs
Abstract: 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.

Quality ATTRIBUTE ACCURACY REPORT:
EDEN real-time water surfaces are created using real-time (one-day delay) water level data for the EDEN network. Most data relayed by satellite or other telemetry have received little or no review. Inaccuracies in the data may be present because of instrument malfunctions or physical changes at the measurement site. A threshold comparison program ... eliminates daily values that appear erroneous (i. e. extremely high or low, extremely different from previous days). Subsequent review of the data may result in significant revisions to the data.
Users are cautioned to consider carefully the provisional nature of the information when using provisional data.
Within approximately 45 days after the end of each quarter (December 31, March 31, June 30, and September 30), finalized and approved water level data are provided by SFWMD and ENP at which time real-time EDEN surfaces will be replaced by provisional surfaces. EDEN surfaces created with final, approved water level data from all agency gages will be available in approximately May of each year for the previous year's water year (October - September).
Access Constraints None
Use Constraints None. All data through 9/30/2007 are final. The data from 10/1/2007 to 12/31/2007 are provisional. Real-time data are available for 2008.
