Everglades Depth Estimation Network (EDEN) for Support of Biological and Ecological Assessments

Water Surfaces

For More Information: "Spatially Continuous Interpolation of Water Stage and Water Depths Using the Everglades Depth Estimation Network (EDEN), University of Florida, IFAS,CIR1521.

Spatially continuous interpolation of water surface across the greater Everglades is generated for daily median values of the water level gages for the EDEN network beginning January 1, 2000. Surfaces are recorded as elevation in centimeters relative to North American Vertical Datum of 1988 (NAVD 88). More information on how water surfaces are created is available below.

Download Data

Data is available in two different formats, in addition to metadata information:

• NetCDF
• GeoTiff
• Metadata (for water surfaces)

We are also providing the daily median output files, which are in turn used as input files for creation of the surface layers. These files show which stations were or were not used for a given day's surface creation.

NetCDF Files:

NetCDF (Network Common Data Form) is a set of freely-distributed software libraries and machine-independent binary data formats that support the creation, access, and sharing of large array-oriented scientific data. This format replaces the bulky file structure and difficult file management of ESRI GRIDS for EDEN data. It also allows EDEN applications to run on computers without ArcGIS installations.

Each file contains 3 months (one quarter-year) of daily datasets. So, for example, the data for every day in 2002 will be stored in 4 files: 2002_q1.nc, 2002_q2.nc, 2002_q3.nc, and 2002_q4.nc. In addition, each zip file contains a readme file which contains brief information about release notes related to this data release.

GeoTiff

Water-level data for all the EDEN gages is retrieved from an ftp server.
Water-level data reported in NGVD 29 are converted to NAVD 88
Daily median water level is calculated.
Linear interpolation is used to create boundary conditions along canals and levees.
Radial Basis Function multiquadric interpolation of extended data (median water level from gages in marsh and interpolated values along canals) is used to generate continuous water level surfaces daily.
The continuous water surface is predicted on the EDEN grid (400 m x 400 m).
Water depth is estimated by subtracting the EDEN ground digital elevation model (DEM) from the predicted water surface.
