Funny that... there was a recent documentary made in Southern America , using state of the art equipment, telescopes lasers etc, the pieces of land that they were testing were indeed FLAT. Worth a watch. Think it was called convex earth the documentary. Many tests were done. Also here is a map found recently in a temple thousand years old, shows earth flat with more land outer Antarctica. Just how like Admiral Byrd of the US fleet mentioned in a live interview and in his death diaries.
