NCEI's ETOPO1 is a 1 arc-minute global relief model of Earth's surface that integrates land topography and ocean bathymetry. It was built from numerous global and regional data sets, and is available in "Ice Surface" (top of Antarctic and Greenland ice sheets) and "Bedrock" (base of the ice sheets) versions.

Dec 14, 2009 · The Global Land One-km Base Elevation (GLOBE) project has developed a 1-km gridded, quality-controlled global Digital Elevation (DEM).

The new topographic map is visually quite different from the satellite gravity field. Isostatically compensated topography stands out in full relief, and edges are sharper due to the inclusion of ship data and the downward-continuation of the gravity field.

NOAA's National Centers for Environmental Information (NCEI) (formerly the National Geophysical Data Center) and collocated World Data Service for Geophysics offer all types of marine geological and geophysical data from the global sea floor and lakebed environments.

Topographic data sets used in compiling the ETOPO1 Global Relief Model were obtained from NGDC, NASA, and the National Snow and Ice Data Center (NSIDC; Table 4).

NOAA's National Centers for Environmental Information (NCEI) compiles bathymetry, topography, relief, and elevation models. Products include imagery, posters, slides, GIS layers, digital models, grids, and contours

Clicking on a square above brings up a 512 x 512 pixel color relief image of the 45 degree area selected, clicking on the 512 x 512 image brings up the full-resolution 1350 x 1350 pixel (roughly 3 mb) color image of the area. go to more global relief images, spinning globes, and posters
