[QUOTE="jayem, post: 74744235, member: 8344"] You don't need azimuth measurements to see evidence that the planet is spherical (or, to be more accurate, spheroidical.) Just watch a cruise ship sailing away from port on a clear day with a good pair of binocs. As the ship departs, you first lose sight of the hull. As it gets farther away, the superstructure disappears. Finally, all you can see are the the topmost parts of the masts, until they're also gone from view. If the ship was sailing on a flat surface, the image would get smaller and smaller, but the entire ship would still be visible. That never happens. The ship always disappears from view in stages, starting with the lowest parts to the highest. That's only possible if the vessel is on a downward trajectory as the distance from the observer increases. Which indicates that it's sailing away on a convexly curved surface. [/QUOTE]
