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. It contains two elevation bands: ice_surface and bedrock.
|bedrock||Elevation at ground level and at the base of the Antarctic and Greenland ice sheets||Meters|
|ice_surface||Elevation at ground level and at the top of the Antarctic and Greenland ice sheets||Meters|
