The Everglades Depth Estimation Network, EDEN, is designed to relate daily continuous surfaces of water level to a U.S. Geological Survey (USGS) elevation data collection for approximately 8,100 square kilometers within the Everglades and to convert those water levels to water depths. These data will provide RECOVER MAP scientists and principal investigators with spatially-continuous real-time hydrologic data and information through an interactive web-based GIS map.

The EDEN User Interface (UI) application (EDENapps) serves two main purposes. It is the means by which the user communicates with the server to obtain water surface, water depth, and days since last dry-down data and it is the medium by which users will view and analyze this data. The target users are biology and ecology investigators examining tropic level response to hydrodynamic change in the Everglades. EDENapps performs these tasks from a desktop application which allows the users to specify an area of interest (AOI) and a time period of interest (TOI) and then returns the appropriate depth data layer(s) from USGS servers.

EDENapps provides functions that allow the user to derive additional information from the downloaded hydrologic layers, including spatially-varying (1) recession rates, (2) number of dry days in the TOI, (3) water level standard deviation, and (4) water volume. Downloaded and user-generated data layers are displayed on demand in side-by-side viewers that allow rapid comparisons of the different layers of information or of the same layer at different times. Query functions allow the user to interact with the mapped data layers to generate hydrographs at specified locations. A report generator produces graphical files of map projects and exports data in formats required for input to external programs, such as spreadsheets and statistical packages.

EDENapps version 1.5 is in the review process with biologists and decision-makers expected to use EDEN products in CERP. The application is also being previewed at the EDEN booth at the 2006 Greater Everglades Ecosystem Restoration Conference and comments are encouraged from GEER participants.
