@BADecker, that link you posted is nonsense and lies. It completely disregards the optical compression that occurs at the angular resolution limit of the eye or camera then starts claiming it's the earth that's curving. The article then goes on to fake a horizon drop with a smartphone theodolite app zeroed off-centre.
The icing on this cake of shit is the illustration they provide:
LOL
All that you are saying is that sighting with transit, and then calculating the measurements, doesn't work. If in your mind it doesn't work, why are you so intent on the idea that the earth is flat. Since sight and sight measurement doesn't work, are you smelling that the earth is flat?
You rely on Youtube videos that you say show the earth is flat. Yet you want to disregard cellphone stuff that's in an article that I mentioned. Yet the cellphone stuff isn't really the important part of the measuring in the article.
The thing that you are really doing is to negate anything that you say by negating the things that I say? How are you doing this? We are both using similar measurement methods. If you negate my using of them, you negate your using of them.
Mine work. Yours don't. In addition, your picture doesn't illustrate what I said.
