Integrating EDEN with Real-Time Hydrology and Biological Responses

The Everglades Depth Estimation Network (EDEN) is an integrated network of real-time water-level monitoring, ground elevation modeling, and water-surface modeling that provides scientists and managers with current (1999-present), on-line water-depth information for the entire freshwater portion of the Greater Everglades. Presented on a 400-square-meter grid spacing, EDEN offers a consistent and documented dataset that can be used by scientists and managers to: 1) guide large-scale field operations, 2) integrate hydrologic and ecological responses, and 3) support biological and ecological assessments that measure ecosystem responses to the implementation of the Comprehensive Everglades Restoration plan (CERP).

Data from this project include water levels (gage), ground elevation (DEM), water surfaces, real-time water surfaces, EDEN grid, hindcasted data, historic hourly data (2000-2005), and meteorological data (rainfall and evapotranspiration).

In addition, a number of applications have been developed to assist in using the EDEN spatial data layers. EDENapps includes:

1. DataViewer - Displays EDEN data layers including panning, zooming, and animation of multiple dates of water surface, depth, and days since dry; queries of data values, and generation of time-series graphs.

2, xyLocator - Returns values from EDEN data layers at specific x,y coordinates over a specified time period. Users can input a file with a list of sample site locations.

3. Transect Plotter - Select a point-to-point transect (not necessarily a straight line) and plot EDEN data profile over the time series, including animation, plotting of observer data, and ground slope.

4. NetCDF to Grid - NetCDFtoGrid is a program for converting EDEN water level, water depth, and days since dry files from EDEN NetCDF files to ESRI Grid files

5. Depth & Days Since Dry - a program for creating daily surfaces (in NetCDF file format, .nc) of water depth and days since dry from EDEN daily water level surfaces and ground elevation model.
