Topography of the Earth at 10 arc-minute resolution
The grid is global with node spacing of 10 arc-minutes (grid-node registered) and stored in netCDF with CF-compliant metadata.
The values are derived from a spherical harmonic model of the ETOPO1 bedrock grid. Topography/bathymetry values are referenced to “sea level” and are positive upwards. The horizontal datum is WGS84.
There are 1081 x 2161 grid points in total. Coordinates are longitude and latitude (geodetic).
