| class="" colspan="3"| ETOPO5 (Earth Topography 5-minute) is a gridded elevation (land) and bathymetry (sea floor) data set for the entire Earth at a grid spacing of 5 minutes (1/12 of a degree or 300 arcseconds). The entire data set consists of a single file which has 4320 columns and 2160 rows. This data set was compiled using data from many different sources by the National Geophysical Data Center (NGDC), which is part of the National Oceanic and Atmospheric Administration (NOAA). Most of the data set dates to 1988, except for a small area in Canada that was regridded in 1990. Elevation values are stored in a flat binary file (row major, no header) as signed 2-byte integers, and are available with both the LSB (least significant byte first) and MSB (most significant byte first) byte orders. The elevation units are meters.<br>Note - The newer GLOBE and GTOPO30 data sets also provide global coverage at the much higher resolution of 30 arcseconds.

| class="" colspan="3"| GLOBE is an international effort to create a global digital elevation model (DEM) on a nominal 1-kilometer grid. Data from a variety of sources was compiled and independently peer-reviewed to provide 30 arcsecond grid spacing, which corresponds to approximately one kilometer near the equator. GLOBE Version 1.0 was completed and released in 1999. GLOBE is an activity of the Committee on Earth Observation Satellites (CEOS), and is part of Focus 1 of the International Geosphere-Biosphere Programme's Data and Information System (IGBP-DIS).<br>GLOBE coverage is divided into sixteen tiles. Each tile spans 90 degrees of longitude has 10800 columns. Tiles bordering the equator span 50 degrees of latitude and have 6000 rows, while the remaining tiles span 40 degrees and have 4800 rows. Elevation data is stored as signed 2-byte integers in flat binary (row major) files with the LSB (least significant byte first) byte order and units of meters. Header files for several formats are also available. Bathymetric data is not yet included but is planned for a future version of GLOBE.
