Summary

The Everglades Depth Estimation Network (EDEN) produces daily depth estimates for the Greater Everglades. This data release includes geospatial data to produce depth estimates for the EDEN from updated digital elevation models. The data release includes three main types of data: 1) 10-m digital elevation models (DEMs) with elevation uncertainty treatment; 2) 50-m DEMs with elevation uncertainty treatment; and 3) spatial metadata for the DEMs used. Specifically, this dataset includes accuracy information by zone. These data address elevation error by using Monte Carlo simulations with 1,000 iterations with observations of elevation error in vegetated wetlands and assumptions error in vegetated non-wetland areas and non-vegetated areas.

Purpose

Elevation estimates in coastal wetlands generally have a high amount of elevation error, which leads to overestimates in elevation (Enwright et al., 2024). These issues can be especially problematic when using DEMs for estimating water depths as is done by EDEN. Besides enhancing EDEN water depth estimates, these data could be useful for sea-level rise impact studies, ecological modeling, and more advanced hydrodynamic modeling efforts.
