ETOPO Global Relief Model

The ETOPO Global Relief Model integrates topography, bathymetry, and shoreline data from regional and global datasets to enable comprehensive, high resolution renderings of geophysical characteristics of the earth’s surface. The model is designed to support tsunami forecasting, modeling, and warning, as well as ocean circulation modeling and Earth visualization.  The current version, ETOPO 2022, is available in Ice Surface and Bedrock versions that portray either the top layer of the ice sheets covering Greenland and Antarctica, or the bedrock below.

The Global Land One-kilometer Base Elevation (GLOBE) dataset is a global digital elevation model (DEM) with 30 arc-second (30") grid resolution. It was the first publicly available, high resolution DEM to cover more than two-thirds of the earth’s surface, though copyrighted or limited distribution products like NIMA predated it. GLOBE data comes from 11 sources, via 18 combinations of source/lineage processing. Scientists compiled DEMs available at griddings of 1-km or smaller, adding or making the best available grids for other areas to complete global coverage of land areas. Organizations from around the world contributed in some way to source data or post-source processing and quality control that ultimately found their way into GLOBE.

Additional Data

Documentation

Sources

Source data — including satellite imagery, aerial photography, satellite altimetry, cadastral survey data, and digitized topographic maps— were converted to 16-bit binary raster grids through stereo-profiling, image pattern recognition, contour-to-grid, point-to-grid surface generation, and a variety of other techniques.

Selection of GLOBE Data

Many areas multiple candidate datasets, which were compared before final selection and mosaicked into the full global DEM. The CEOS GLOBE Task Team and IGBP-DIS. The final product received peer review on four continents.
