The Center for Coastal and Ocean Mapping [1] (CCOM) / NOAA-UNH Joint Hydrographic Center (JHC) was founded in 2000 by Dr. Larry Mayer to find ways to process the massive amounts of data coming from sonar systems at rates commensurate with data collection; that is, to make the data ready for chart production as rapidly as the data could be collected.
The National Geodetic Survey is an office of NOAA's National Ocean Service.Its core function is to maintain the National Spatial Reference System (NSRS), "a consistent coordinate system that defines latitude, longitude, height, scale, gravity, and orientation throughout the United States". [1]
The Office of Coast Survey employs about 250 United States Government employees and about 50 contractor personnel. [3] It is organized into four components: [3] The Marine Chart Division, responsible for processing nautical data, producing raster, paper, and electronic charts, and making critical corrections to charts.
Animated models show nearly 200 coastal cities drowned by rising sea levels. Katie Hawkinson. December 1, 2023 at 3:21 PM.
A global relief model, sometimes also denoted as global topography model or composite model, combines digital elevation model (DEM) data over land with digital bathymetry model (DBM) data over water-covered areas (oceans, lakes) to describe Earth's relief. A relief model thus shows how Earth's surface would look like in the absence of water or ...

Since the Sea Level Datum of 1929 was a hybrid model, it was not a pure model of mean sea level, the geoid, or any other equipotential surface. Therefore, it was renamed the National Geodetic Vertical Datum of 1929 (NGVD 29) May 10, 1973, by the National Geodetic Survey , a part of the National Oceanic and Atmospheric Administration .
The National Oceanic and Atmospheric Administration (NOAA / ˈ n oʊ. ə / NOH-ə) is an American scientific and regulatory agency charged with forecasting weather, monitoring oceanic and atmospheric conditions, charting the seas, conducting deep-sea exploration, and managing fishing and protection of marine mammals and endangered species in the US exclusive economic zone.
