#### Description

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.

### Bands

**Bands**

Pixel size: 1855 meters (all bands)

| Name | Units | Min | Max | Pixel Size | Description |
|---|---|---|---|---|---|
| `bedrock` | m | -10898\* | 8271\* | 1855 meters | Elevation at ground level and at the base of the Antarctic and Greenland ice sheets |
| `ice_surface` | m | -10898\* | 8271\* | 1855 meters | Elevation at ground level and at the top of the Antarctic and Greenland ice sheets |

\* estimated min or max value
