Everglades Depth Estimation Network (EDEN) November 2007 Digital Elevation Model for use with EDENapps

This is the 1st release of the third version of an Everglades Depth
Estimation Network (EDEN) digital elevation model (DEM) generated from certified airborne
height finder (AHF) and airboat collected ground surface elevations for the Greater
Everglades Region. This version includes all data collected and certified by the USGS prior
to the conclusion of the AHF collection process. It differs from the previous elevation
model (EDEN_EM_JAN07) in that the modeled area of WCA3N (all the WCA3A area north of I-75)
is increased while the modeled area of the Big Cypress National Preserve (BNCP) has been
both refined and reduced to the region where standard error of cross-validation points falls
below 0.16 meters. EDEN offers a consistent and documented dataset that can be used to guide
large-scale field operations, to integrate hydrologic and ecological responses, and to
support biological and ecological assessments that measure ecosystem responses to
Comprehensive Everglades Restoration Plan. To produce historic and near-real time maps of
water depths, the EDEN requires a system-wide DEM of the ground surface. This file is a
modification of the eden dem released in October of 2007 (i.e., eden_em_oct07) in which the
elevation values have been converted from meters (m) to centimeters(cm) for use by EDEN
applications software. This file is intended specifically for use in the EDEN applications
software. Aside from this difference in horizontal units, the following documentation
applies.

These data were specifically created for the development of water depth information using interpolated water surfaces from the EDEN stage data network.
