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. |
