This is an interactive tool to plot three-dimensional bottom topography based on ETOPO2v2 dataset. The dataset was published by the National Geophysical Data Center, NOAA, USA, and contains land height and ocean depth of 2-minute grids. For more details, access www.ngdc.noaa.gov.

Please specify plotting parameters. Wider region needs much more time in producing the image!

• Latitudes from to (-90 to 90).
  Longitudes from to (-180 to 360, e.g., -10 to 10 to cross Greenwich).
• Maximum depth is m.
• View angle of horizontally (-45 to 45) and vertically (0 to 90), but really this angle is not accurate.
• Aspect ratio of vertical to horizontal scale .
• Which dataset do you want? original 2min data averaged for 4min grids averaged for 10min grids averaged for 20min grids averaged for 30min grids averaged for 1deg grids
• You can specify the size of images. Which factor do you want? 1.0 2.0 4.0

the map, but it takes a little time. Please wait....

You can also make a image using the Generic Mapping Tools. Which type do you want? not GMT GMT Horizontal view GMT Bird view (mesh) GMT Bird view (surface)
