Short Description
 |
| ETOPO1 Global Relief Model |
Statement: Integrated bathymetric-topographic global relief model; 1 arc-minute (~2 km) cell size
Abstract: 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.
