Coastal elevation profiles were measured at previously established locations. Other data points are categorized as base station, bathymetry, benchmark, camera calibration data, community-based monitoring profile, drainage observation, flood staff, ground control point, miscellaneous, and water level. The elevation data were collected with real-time kinematic global navigation satellite system (RTK-GNSS) equipment. Data are available in a single CSV file per community.",

Bathymetry is the elevation of the Earth's surface beneath a body of water, especially the ocean, typically determined by measurements of depth from the water surface at mean lower low water. Distributions are topographic maps and bathymetric charts based on collected data and also include smoothed or gridded maps of bathymetry and elevation from observational data or other associated factors. Assessment data types include models of ecological value, economic value, or current rates of alterations due to erosion, accretion, climate change, and other stressors (for example, wetland habitat loss). Predictions are the results of models or projections of future distributions, values, or ecological impacts of bathymetry, including predicted changes due to natural and human forces such as erosion, deposition, sea-level rise, and dredging activities; predictions also include the results of scenario-based models of bathymetry changes under different management strategies."
