ETOPO : Data Information



ETOPO2v2 is a 2-minute gridded global relief model of Earth's surface that integrates land topography and ocean bathymetry. It was built from numerous global and regional data sets. The horizontal datum is WGS-84, the vertical datum is Mean Sea Level. The original coverage of ETOPO2v2 is 90 S to 90 N in latitude, and 180 W to 180 E in longitude.
