Can we abandon that line of thought for one moment? Like I said, it's not about the shape of the Earth. Those longitudinal lines wouldn't have to deviate as approaching the edge on any flat map.
You keep making vague statements like that, we'll put up or shut up!
Show us this
flat earth map where those longitudinal lines do not deviate as approaching the edge of the flat map.Therein lies your problem. You seem to ignore those lines altogether. Because you ignore these lines, you try to do things like measure by using un-scaled straight lines, which makes you look silly.
I do not have a problem at all, you will not face the simple fact that if the earth were flat, a flat map is simply a scale drawing of the earth.
Then any measurement between two points on the map with a ruler can be simply scaled up by the scale factor.
That is exactly what can be done on a map of a limited region of the Globe.
The problem is that on the Globe, flat maps of necessity all have scale distortion in some or all directions.
Please read, learn and inwardly digest,
Geokov, Education, Map Projections - types and distortion patternsIf the earth were flat the scale factor of any flat map would be constant over the whole map.
Please stop doing that. You're essentially arguing against a round Earth model. Seems counterproductive when you consider your position on that matter, no?
No, I am not "arguing against a round Earth model"!
If you think that I am wrong, post a flat earth map and show why I am wrong.
But you never do that. You are all empty words.
If the earth were flat and shaped as in the "Ice-Ring map" then distances can simply be scaled up using the scale-factor of the map.
That scale-factor can easily be determined from the 24,900 mile diameter of the "known earth" in
the Wiki. The 24,900 mile figure agrees closely with the corresponding measurement on the Globe, the polar circumference.
Australia Dimensions - Ice Ring MapSo from a map like this we can scale from that 24,900 miles to get the dimensions of say, Australia.
Actually, for more accurate results, I calculate the distances from lat/long, same result, but more accurate.
Now, if you disagree, please show exactly how you would find distances on that or any other flat earth map.
