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

Network of Benchmarks Used to Evaluate and Verify the EDEN Surface-Water Model

An alphabetical listing of benchmarks is available below. Instructions for using the map are below.
A network of benchmarks was established in the marshes of the greater Everglades and surveyed to North American Vertical Datum of 1988 in 2009-2010 to test, validate, and improve the Everglades Depth Estimation Network (EDEN) surface-water interpolation model that creates daily water-level surfaces for the Everglades. Thirty-four benchmarks were installed and surveyed in 2009 and 7 additional benchmarks were installed and surveyed in 2010. When these benchmarks are combined with the 31 benchmarks established by the Florida Department of Environmental Protection in 2006, the network of 72 benchmarks (2nd order or better) provide a geographically broad distribution of points of known elevation and measured water levels independent of the existing water-level gage network.
