Relative Tidal Marsh Elevation Maps with Uncertainty for Conterminous USA, 2010

Published by ORNL_DAAC | National Aeronautics and Space Administration | Metadata Last Checked: February 07, 2026 | Last Modified: 2026-02-03

This dataset provides maps of the elevation of coastal wetlands relative to tidal ranges for the conterminous United States (CONUS) at 30 m resolution for 2010. It also includes maps of tidal amplitude, relative sea-level rise for the period 1983-2001, and maps for coastal lands and low marsh areas based on the probability of being below the mean higher high tide water line for spring tides (MHHWS). Uncertainty layers for elevation maps are also provided.
