Description:
Abstract:
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.

Purpose:
Research has shown that relatively high-resolution data are needed to explicitly represent variations in the Everglades topography and vegetation that are important for landscape analysis and modeling. The EDEN project will provide a better representation of water depths if elevation variation within each 400-meter grid cell can be taken into account.

The EDEN network provides a framework to integrate data collected by other agencies in a common quality-assured database. In addition to real-time network, collaboration among agencies will provide the EDEN project with valuable historic vegetation and water-depth data. This is the first time these data have been compiled and analyzed as a collective set.

Data_Quality_Information:
Logical_Consistency_Report:
The EDEN monitoring network includes ground-elevation measurements, continuous water-level data, water surfaces, real-time water surfaces, hindcasted data, and historic hourly data (2000-2005) for specific stations, rainfall and evapotranspiration data, and the 400 by 400 m grid to which the EDEN data is referenced.
Completeness_Report:
Ground-surface elevation data were collected by the USGS at more than 50,000 points with an approximate spacing of 400 meters covering almost the entire Greater Everglades.

The EDEN water-level network consists of hourly water-level data from over 250 gaging stations and includes freshwater (nontidal) marsh gaging stations, boundary gages on canals, and coastal gaging stations operated by the Big Cypress National Preserve (BCNP), Everglades National Park (ENP), South Florida Water Management District (SFWMD), and USGS. The U.S. Army Corps of Engineers (USACE) and SFWMD recently documented or surveyed a majority of the hydrologic gages in the Greater Everglades to obtain correct values for converting water-level data from NGVD 29 to NAVD 88. The NAVD 88 datum is consistent in comparing water-level data across the Greater Everglades and computing accurate water depths.

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).

The origin and extent of the EDEN grid were selected to cover not only existing Airborne Height Finder (AHF) data from the ground elevation model and current regions of interest for Everglades restoration, but to cover a rectangular area that includes all landscape units and conservation areas in place at the time of its development.

Rainfall data based on Next Generation Radar (NEXRAD) data from the U.S. National Weather Service provides complete spatial coverage of rainfall amounts for the State of Florida. The accuracy of NEXRAD data is enhanced when adjusted using the local rain-gage data. The NEXRAD coverage for the South Florida Water Management District area includes rainfall amounts for 15-minute intervals for the period January 1, 2002 to present for 2 km by 2 km grid resolution. The SFWMD receives 'near real-time' 15-minute data (NRD) continuously. These NRD are compiled, verified, and quality-assured at the end of each month in the end-of-month (EOM) sets of 15-minute files. The EOM files use 81 additional rain gage data that are not available real-time and a proprietary algorithm based on the Brandes method to adjust radar rainfall values.

Evapotranspiration data are available in files from 1995-2004, 2005 - 2008, and 2009.

Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Horizontal positions are established by GPS observations and are referenced to the North American Datum of 1983 (NAD83). The desired horizontal accuracy is +/- 15 centimeters. This level of accuracy is consistent with GPS differential techniques which use two stations - a high-quality dual-frequency GPS receiver base station and a roving GPS station. The density and accuracy of a given GPS data observation varies from a few meters to a few centimeters according to the Position Dilution of Precision (PDOP) in the study area. Generally if the PDOP is observed to be excessive, data collection is discontinued or the data are discarded. The PDOP is an indicator of the positional accuracy of the GPS that be can derived from the current GPS satellite geometry, which varies continuously. Generally the smaller the PDOP number, the higher the data quality. The PDOP is a permanent part of the recorded data and is also included in the post processing procedures during reduction of the GPS observations to NAD 83. Where possible, the GPS base station has an ellipsoid height to an accuracy of two centimeters relative to the Continuously Operating Reference Stations (CORS) or the High Accuracy Reference Network (HARN), both operated by the National Geodetic Survey (NGS).
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Source data (HAED) collected to better than +/- 15cm. Standard errors of cross-validation for the DEM range from ~7cm to 17cm depending on the EDEN subarea. This version is composed of new models created for WCA3N and the BCNP combined with the mosaic of two versions (i.e., eden_v002a for WCA1 and eden_v002c for all other EDEN subregions) that comprised EDEN_EM_JAN07. The previous mosaic was selected based on analysis of model performance in the water depth estimation process. The WCA1 surface was produced by removing all "upland" AHF points as defined by a reclassification of the Florida GAP process. For WCA1, the krigging model was developed based on statistics from the entire EDEN domain (the process for eden_v002a production). For each other EDEN sub-area (i.e., the other WCAs and the National Park) region specific krigging models were developed and applied.
Lineage:
Process_Step:
Process_Description:
The EDEN domain was broken into a large number of equal-sized rectangles (cells) that in total are referred to as the "grid". Characteristics of this grid, such as location of the centroid, the representative area of the Everglades, elevation, and percentage of vegetation type, define the grid spatial parameters. To match the Airborne Height Finder (AHF) data sampling spacing, the spatial resolution or the dimension (in ground distance) of each grid cell is 400 meters on each side. The ground surface DEM development process is iterative as additional high accuracy elevation data (HAED) are collected, water surfacing algorithms improve, and additional ground-based ancillary data become available. The DEMs used in the EDEN analysis through the summer of 2006 rely on version HAEDbeta2 of HAED. However, this version was produced by using all available AHF points posted to SOFIA as of August 2007. To create a realistic region-wide elevation model for EDEN purposes, the elevation data were segregated by Water Conservation Areas and National Park boundaries so that local trends could be isolated, sub-region specific interpolation models could be developed, and realistic breaks in elevation along sub-region boundaries could be imbedded in a final, region-wide DEM, To date the best performing DEMs for all subareas have been produced using the geostatistical approach called "anisotropic ordinary kriging". The latest iteration of the EDEN DEM used in EDEN applications is referenced as eden_em_ja10.

Process_Description:
The water surface model was created by the following steps:

1. Water-level data for all the EDEN gages is retrieved from an ftp server 2. Water-level data reported in NGVD 29 are converted to NAVD 88 3. Daily median water level is calculated 4. Linear interpolation is used to create boundary conditions along canals and levees 5. Radial Bias 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 6. The continuous water surface is predicted on the EDEN grid (400m x 400m) 7. Water depth is estimated by subtracting the EDEN ground digital elevation model (DEM) from the predicted water surface

The USGS retrieves water level data daily from over 250 gaging stations that record and transmit several water level values throughout the day, most hourly from recorders ranging from approximately 81 deg, 07 min 19 sec to 80 deg 13 min 05 sec West and from 25 deg 13 min 27 sec to 26 deg 40 min 47 sec North. An additional 28 gages do not have telemetry and are manually read and added to the network. All transmitted data are entered and stored in the National Water Information System (NWIS), a database operated by the USGS. There are a total of over 250 gages used for water surface interpolation of the freshwater Everglades.

All gages in the EDEN network are operated and maintained by four separate agencies including Everglades National Park, South Florida Water Management District, Big Cypress National Preserve, and the USGS.

Process_Description:
The EDEN monitoring network includes ground-elevation and continuous water-level data. The EDEN water-level network consists of hourly water-level data from over 250 gaging stations and includes freshwater (nontidal) marsh gaging stations, boundary gages on canals, and coastal (tidal) gages operated by the Big Cypress National Preserve (BCNP), Everglades National Park (ENP), South Florida Water Management District (SFWMD), and USGS. All gaging stations have telemetry equipment that provides data on a daily basis. Several of the new gaging stations are co-located where ongoing landscape studies have been conducted for several years. A 6-year (October 1, 1999 to September 30, 2005) dataset of baseline conditions was established for the EDEN water-level network prior to the implementation of CERP.

Water-level gaging stations have been surveyed, until recently, to the National Geodetic Vertical Datum of 1929 (NGVD 29); however, this datum has inconsistencies in the vertical network that have never been resolved for southern Florida. The U.S. Army Corps of Engineers (USACE) and SFWMD recently documented or surveyed a majority of the hydrologic gages in the Greater Everglades to obtain correct values for converting water-level data from NGVD 29 to the North American Vertical Datum of 1988 (NAVD 88). These and other data provided by BCNP and ENP have been used to create datum-correction values for the EDEN network gages, allowing historic water-level data to be converted from NGVD 29 the NAVD 88.

Three methods were used to determine the correction for a gaging station: 1. Differential or basic Global Positioning System (GPS) - a highly accurate satellite-based surveying system 2. Optical survey - a traditional line-of-sight survey from points of known elevation; and 3. CORPSCON 1 version 6.0 - a program that interpolates the difference between ground elevation in NAVD 88 and NGVD 29 for a given location specified by latitude and longitude, and further refined by using the VERTCON version 2.5 grid modified by USACE Jacksonville District to incorporate the CERP vertical control network established in 2001-2002.

Process_Description:
In FY07, the surface model was enhanced and an analysis of confidence identified several problem areas along boundaries. The daily model surfaces will be posted to the EDENweb in October with metadata and full documentation. The process of computing new daily maps will begin on a quarterly basis beginning in FY08.

The current scope of work will continue operation and maintenance of 25 gaging stations and will implement the hydrologic tools to support biological and ecological assessments of the impacts of the restoration plan for the greater Everglades.

Process_Description:
To increase the accuracy of the water-surface models, 25 real-time water-level gaging stations were added to the network of over 250 established water-level gaging stations. To incorporate the data from the newly added stations to the 7-year EDEN database in the greater Everglades, the short-term water-level records (generally less than 1 year) needed to be simulated back in time (hindcasted) to be concurrent with data from the established gaging stations in the database. A three-step modeling approach using artificial neural network models was used to estimate the water levels at the new stations. The artificial neural network models used static variables that represent the gaging station location and percent vegetation in addition to dynamic variables that represent water-level data from the established EDEN gaging stations. The final step of the modeling approach was to simulate the computed error of the initial estimate to increase the accuracy of the final water-level estimate.

The three-step modeling approach for estimating water levels at the new EDEN gaging stations produced satisfactory results. The coefficients of determination (R2) for 21 of the 25 estimates were greater than 0.95, and all of the estimates (25 of 25) were greater than 0.82. The model estimates showed good agreement with the measured data. For some new EDEN stations with limited measured data, the record extension (hindcasts) included periods beyond the range of the data used to train the artificial neural network models. The comparison of the hindcasts with long-term water-level data proximal to the new EDEN gaging stations indicated that the water-level estimates were reasonable. The percent model error (root mean square error divided by the range of the measured data) was less than 6 percent, and for the majority of stations (20 of 25), the percent model error was less than 1 percent.

Other work accomplished in FY 2009 includes:

1. EDEN continues to evaluate new and additional gages that may help fill in gaps in the network of gages used to create the daily water-level surfaces and potentially improve the surfaces. In 2009, EDEN added 5 gages to the network:

BARW4, BARW6A in western Big Cypress National Preserve, G338_T and G251_T in western WCA1, SR1 in Everglades National Park, and TSB replaced TS2, in Everglades National Park

2. EDEN surface water interpolation model program is being updated for new and revised datasets and expanded to include an area south of BCNP to the mangrove ecotone. The expanded area is interpolated consistent with the existing program. This task has been delayed about 6 months because data quality issues required more time to address than expected. Coordination and integration of multi-agency datasets has proven to be more time intensive than expected at this point in the project

3 days per water year (2004, 2007, 2008) are used to represent dry, wet, and average conditions for model calibration. 300-400 runs per day have been completed for the selected 9 days with varying parameter values based on EDEN extended daily medians prior to canal file revisions, including 50 runs randomly selected from 255,744 parameter scenarios. The parameter scenarios and resultant SW grids will serve as reference for evaluating canal file revisions

A USACE contract is in place to collect water level data at approximately 65 benchmarks through the Everglades in wet season 2009, dry season 2010, and wet season 2010. These data will be invaluable to continue the validation process of the EDEN surfacing model

3. EDEN assisted the USACE Survey Section in installation and survey of 34 benchmarks (BMs, surveyed to Class B standards, stainless steel rod driven to refusal) in the Everglades wetland marshes. EDEN compiled the location of BMs, obtained permits where required, and will post all BM elevations and data sheets on the EDENweb

4. Rainfall and evapotranspiration data continue to be updated regularly for the EDEN gage network and posted to the EDENweb

5. Pilot data analysis was begun to review data in Shark River Slough for oligohaline zone analysis

6. EDEN provided hydroperiod maps and mean monthly water depth data for the 2009 System Status Report to assist with hydrologic assessments of component areas of the Everglades and for understanding the total system hydrology

Overview_Description:
Entity_and_Attribute_Overview:
The ground surface DEM contains the location of the grid cell in UTM easting and northing and the altitude value.

The Water Surfaces data in NetCDF have the following attributes: Creation Date, Conventions (version), Source (what software was used to write the file), Layer name, spatial reference (UTM Zone), Datum, Spheroid, Prime Meridian, Angular Units, Projection, Linear Units, False Easting, False Northing, Central Meridian, Scale Factor, Latitude of Origin, Grid Mapping Units, Starting Date (for the data), and Time Step Units. The data are also available as Geotiff files. The Daily Median Output Files contain 3 months of daily datasets. There are two files for each day: a "median" and a "median_reject". The "median" file is the one that was used to create the surface for a given day, the "median_reject" file contains a list of the gages not used for that day.

The Water Level (Gage) data for each area have a graphic showing the location of the gages and whether they are real time or non-real time and a list of the stations in each area. The information for each station includes station information, data links, data information, ground elevation/vegetation, and other information available for the station.

Information for rainfall collection is arranged by date and collection site within the following areas: Big Cypress National Preserve, Everglades National Park East and West, Florida Bay, Gulf of Mexico, Pennsuco Wetlands, and Water Conservation Areas 1, 2, and 3. Data are available starting in 2002 and are available by month within approximately 45 days after the end of each month.

Evapotranspiration data are available for Big Cypress National Preserve, Everglades National Park East and West, Florida Bay, Gulf of Mexico, Pennsuco Wetlands, and Water Conservation Areas 1, 2, and 3 from 1994 - 2009.

Hindcasted measured data include the date and time of collection and the water level in feet related to NAVD 88 measured at the gaging station. The extended record combines the measured data (provisional) with the filled hindcasts. Periods of missing data are completed with filled hindcast or interpolated data in feet NAVD 88.
