Let me clarify. It is not about the map projection. In euiv, vic2 etc... you can take a ship and like Magellan circumnavigate the globe. I.e. sail west and end up at the same place. That is the map represent the world as a globe. The IR map crops the edges as inaccessible. Is that the only thing that stops a circumnavigation or is it an actual flat earth - have any one investigated this?
