ETOPO2, Global 2 Arc-minute Ocean Depth and Land Elevation from the US National Geophysical Data Center (NGDC)

Global elevation and bathymetry on 2 arc-minute grid from the National Geophysical Data Center (NGDC). This dataset was original published in September 2001 and was revised to include correction to Caspian Sea area in April 2006. It contains improvements that include the blending of satellite altimetry with ocean soundings and new land elevation data from the Global Land One-km Base Elevation (GLOBE) project.
