2-minute Gridded Global Relief Data (ETOPO2) v2

browse graphicThumbnail of DEM
This version has been superseded by a newer version. It is highly recommended for users to access the current version. Users should only access this superseded version for special cases, such as reproducing studies. Two-minute gridded global relief for both ocean and land areas are available in the ETOPO2v2 (2006) database. ETOPO2v2 replaced ETOPO2 (2001). The historic 2-minute (ETOPO2v2) and 5-minute (ETOPO5) data are deprecated, but still available.
