ETOPO1 (Earth Topography 1-Minute)DescriptionETOPO1 (Earth Topography 1-minute) is a gridded elevation (land) and bathymetry (sea floor) data set for the entire Earth in a single file. It was compiled using data from many different sources by the National Geophysical Data Center (NGDC) of the National Oceanic and Atmospheric Administration (NOAA). Note that the GLOBE and GTOPO30 data sets also provide global coverage at the higher resolution of 30 arcseconds, but without bathymetry or floating-point values. Grid Information
