[edit] Summary

This image shows the route, in red, of a typical sailing circumnavigation of the world via the Panama Canal and Suez Canal, making use of the trade winds. Shown in yellow is the antipodean point of each point on the route; it can be seen that a boat following this route will pass through several points antipodean to each other, thus satisfying one definition of a circumnavigation.

This image was constructed from a public domain Visible Earth product of the Earth Observatory office of the United States government space agency NASA. It is based on a cylindrical equi-distant projection.

Public domain This image is in the public domain because it is a screenshot from NASA's globe software World Wind using Blue Marble, Landsat or USGS layer, each of which is in public domain.
