In August 2008, the National Geophysical Data Center (NGDC), an office of the National Oceanic and Atmospheric Administration (NOAA), developed the ETOPO1 Global Relief Model as an improvement to the ETOPO2v2 Global Relief Model. ETOPO1 is available in "Ice Surface" (top of Antarctic and Greenland ice sheets) and "Bedrock" (base of the ice sheets) versions. Both versions of ETOPO1 were generated from diverse global and regional digital data sets, which were shifted to common horizontal and vertical datums, and then evaluated and edited as needed. Bathymetric, topographic, and shoreline data used in ETOPO1 were obtained from NGDC, Antarctic Digital Database (ADD), European Ice Sheet Modeling Initiative (EISMINT), Scientific Committee on Antarctic Research (SCAR), Japan Oceanographic Data Center (JODC), Caspian Environment Programme (CEP), Mediterranean Science Commission (CIESM), National Aeronautics and Space Administration (NASA), National Snow and Ice Data Center (NSIDC), Scripps Institute of Oceanography (SIO), and Leibniz Institute for Baltic Sea Research (LIBSR). ETOPO1 is vertically referenced to sea level, and horizontally referenced to the World Geodetic System of 1984 (WGS 84). Cell size for ETOPO1 is 1 arc-minute.

publisher
The DEM Global Mosaic is an image service providing a global, seamless bathymetry/topography mosaic that includes NCEI's ETOPO 2022, NCEI's Continuously Updated DEM (CUDEM), and other NCEI-stewarded DEMs, along with regional grids such as IBCAO, IBCSO and the Hawaiian Island Multibeam Synthesis (University of Hawaii). This service provides elevation/depth values in meters; for a visualization of the data, please see the related DEM Global Mosaic (Color Shaded Relief) service. There are 5 related image services providing access to Digital Elevation Models: DEM Mosaic (Individual DEMs), DEM Global Mosaic (Elevation Values), DEM Global Mosaic (Color Shaded Relief), CUDEM Mosaic (Elevation Values), and CUDEM Mosaic (Color Shaded Relief). NCEI builds and distributes high-resolution, coastal digital elevation models (DEMs) that integrate ocean bathymetry and land topography to support NOAA's mission to understand and predict changes in Earth's environment, and conserve and manage coastal and marine resources to meet our Nation's economic, social, and environmental needs. They can be used for modeling of coastal processes (tsunami inundation, storm surge, sea-level rise, contaminant dispersal, etc.), ecosystems management and habitat research, coastal and marine spatial planning, and hazard mitigation and community preparedness. This service is a general-purpose global, seamless bathymetry/topography mosaic. It combines DEMs from a variety of near sea-level vertical datums, such as mean high water (MHW), mean sea level (MSL), and North American Vertical Datum of 1988 (NAVD88). No conversion/harmonization of vertical datums was performed. Because the mosaic contains 'overviews' for performance, individual DEMs cannot be separated from the others. Individual DEMs, or smaller subsets, are available in the companion DEM Mosaic (Individual DEMs) image service. By default, the DEMs are drawn in order of cell size, with higher-resolution grids displayed on top of lower-resolution grids. If overlapping DEMs have the same resolution, the newer one is shown. Please see NCEI's corresponding DEM Footprints feature service for polygon footprints and more information about the individual DEMs used to create this composite view.

Horizontal Positional Accuracy Report
The horizontal accuracy of bathymetric and topographic features in the global relief model is dependent upon the accuracy of the input datasets used to determine corresponding cell values. A qualitative assesment of horizontal accuracy was performed, but a quantitative assesment has not yet been performed. Topography: Positional accuracy of input topographic datasets limits accuracy of corresponding cell values in global relief model. Global relief model topographic cell-value relative-contribution factors: NASA SRTM30: 1, NGDC GLOBE: 1, NISDC Antarctica RAMP: 100, NGDC IBCAO: 10, NGDC Great Lakes: 10. Bathymetry: Positional accuracy of input bathymetric datasets limits accuracy of corresponding cell values in global relief model. Global relief model bathymetric cell-value relative-contribution factors: JODC bathymetry: 10, NGDC Gulf of California Bathymetry: 10, CEP Caspian Sea Bathymetry: 10, CIESM Mediterranean Sea Bathymetry: 10, SIO Measured and Estimated Seafloor Topography: 1, LIBSR Baltic Sea Bathymetry: 10, NGDC IBCAO: 10, NGDC U.S Coastal Relief Model: 10, NGDC Great Lakes Bathymetry: 10.
Vertical Positional Accuracy Report
The vertical accuracy of bathymetric and topographic features in the global relief model is dependent upon the accuracy of the input datasets used to determine corresponding cell values. A qualitative assesment of vertical accuracy was performed, but a quantitative assesment has not yet been performed. Vertical accuracy of input topographic datasets limits accuracy of corresponding cell values in global relief model. Global relief model topographic cell-value relative-contribution factors: NASA SRTM30: 1, NGDC GLOBE: 1, NISDC Antarctica RAMP: 100, NGDC IBCAO: 10, NGDC Great Lakes: 10. Bathymetry: Vertical accuracy of input bathymetric datasets limits accuracy of corresponding cell values in global relief model. Global relief model bathymetric cell-value relative-contribution factors: JODC bathymetry: 10, NGDC Gulf of California Bathymetry: 10, CEP Caspian Sea Bathymetry: 10, CIESM Mediterranean Sea Bathymetry: 10, SIO Measured and Estimated Seafloor Topography: 1, LIBSR Baltic Sea Bathymetry: 10, NGDC IBCAO: 10, NGDC U.S Coastal Relief Model: 10, NGDC Great Lakes Bathymetry: 10.
NGDC made every effort to obtain all available digital topographic and bathymetric datasets for use in building the global relief model.
Datasets were visually compared internally and externally (with other overlapping datasets and satellite images and maps) in ESRI ArcGIS for identification of anomalous elevations or data inconsistencies. Where elevation inconsistencies occurred, the most recent and/or highest resolution data set was selected for use in that region. Elevations in the older and/or lower-resolution datasets were deleted prior to building the global relief model.
All datasets obtained by NGDC were converted to common horizontal and vertical datums of WGS 84 and sea level, respectively, using FME. They were also converted to common file format, ESRI point shapefiles, for visualization and inspection.

Datasets were visually inspected with ArcGIS for identification and editing of data anomalies. Datasets were then compared with overlapping datasets to ensure data consistency.
2008-06-25T00:00:00
Coastline datasets were adjusted to fit satellite imagery.
2008-06-30T00:00:00
xyz files of the Measured and Estimated Seafloor Topography data (between -500 m and 0 m) were surfaced using GMT's 'surface' tool onto a 1 arc-minute cell size grid that interpolated to fill empty cells. Points extracted along the GSHHS coastline were also included, at -1 m elevation, to force bathymetric interpolation into the coastal zone. The resulting Arc ASCII grid was clipped to the coastline and the -120 m contour to remove values over land and non-coastal waters.
2008-07-10T00:00:00
xyz files for each input dataset were gridded using MB-System's 'mbgrid' tool, which utilizes a high-tension spline interpolation method to fill grid cells with no input elevation values. Preferential weighting was given to the NSIDC Antarctica RAMP topography dataset. Least weight was given to the global datasets and the interpolated bathymetric surface. Gridding was performed in 16 regional tiles, each with a 5% data buffer. The grids were imported in ArcGIS and seamlessly merged to create the final global relief model.
2008-07-18T00:00:00
ETOPO1 was bult as a global, grid-registered, 1 arc-minute grid that spans from pole to pole and from -180 degrees to 180 degrees in longitude. It is 21601 cells by 10801 cells in dimension, with multiple duplicate cells sitting atop the North and South poles and on the -180 degrees and 180 degrees longitude line. A cell-registered version (21600 by 10800 cells) was created from the grid-registered version by resampling, using GMT's 'grdsample' tool. This resampling introduces some flattening of relief, due to averaging of four grid-registered cell vlaues to produce one cell-registered value. Both types are global, though the grid-registered version should be considered the authoritative version. The cell-registered version may be more appropriate for creating maps and images.

Data Stewardship Maturity Assessment
MM-Stew
The Data Stewardship Maturity Matrix (DSMM) is a unified framework that defines criteria for each of nine components based on measurable practices, which can be used to apply a progressive, 6-level rating to an individual dataset, representing stewardship maturity stages rated as Not Assessed or Not Available (Level 0), adHoc (Level 1), minimum (Level 2), intermediate (Level 3), advanced (Level 4), and optimal (Level 5).
Data Stewardship Maturity Assessment was evaluated by the metadata content editor for the NOAA OneStop project using the Scientific Data Stewardship Maturity Assessment Model Template v4.0.
