No, Mr Totally Lacking, you claimed, "Any map presented to any explorer south of the Equator has errors to this day" so you have not made a case especially when you go on to say "that explorer will soon find themselves off-heading, sometimes up to several hours of travel time".
You posted one video indicating that in one remote location one chart may be 200-300 m in error!
So what?
Because the specific example I provided demonstrated exactly that...
No! I repeat that you showed ONE example. You did not show that:
Any map presented to any explorer south of the Equator has errors to this day (becoming fewer and fewer) and that explorer will soon find themselves off-heading, sometimes up to several hours of travel time.
The reason? The explorer ASSUMES A SPHERICAL EARTH, rather than just trusting the flat map.
Please tell us about this secret accurate "flat map" the "The explorer" should be "trusting"!
I thought that there was no definitive flat earth map!
All maps contain errors because they are man-made.
That I will grant you, but all diagrams and even engineering drawings contain "error".
Any map can only be as accurate as the best survey of the region.
Before satellite mapping there was no better method of finding a location in a remote region of the earth than
celestial navigation.
According to all I can find that accuracy can never be better than to within about ±200 m.
From a number of base locations, geodetic surveyors can then map out the rest of the region. When aerial mapping became feasible that was used to fill in the detail.
So it is unlikely that navigation charts in the pre-satellite mapping era ever had an absolute accuracy better than this ±200 m whatever the shape of the earth.
And even that ±200 m is very optimistic.
nor that "that explorer will soon find themselves off-heading, sometimes up to several hours of travel time".
Specific example already posted.
Now Mr Totally Lacking, This morning I saw a video of a white rabbit. So, according to your logic all rabbits are white.
False equivalency.
Not "False equivalence" because if I find a
chart that does not have significant errors I disprove the claim that claim that "
Any map presented to
any explorer south of the Equator has errors
to this day".
All I have to do if present that map "to
any explorer south of the Equator" and your case is blown out of the water.
But all you seem interested in is "scoring points" and that does nothing towards settling the Flat/Globe shape of the earth.
If you could present a flat earth map that was as accurate as the pre-satellite mapping maps of countries it would help your case no end.
I have a fairly high-resolution map of Australia published in 1855.
Simply scaling from that map gives the width of Australia along the 30°S latitude to within about 30 km of current the value.
Show me any FE map of comparable accuracy.And in closing,
Mr Totallackey, you are an
ignorant idiot if you think that
Geoff and I are the same person.
Bye bye
Mr Totally Lost it!
