2-minute Gridded Global Relief Data (ETOPO2) v2

browse graphicMosaic of 32 total, 45-degree squares of color shaded relief images, other images at http://www.ngdc.noaa.gov/mgg/image/globalimages.html
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. Please use the new ETOPO1 Global Gridded Relief Model.
