No map is perfect. But it just seems odd watching you on your side of the fence, demand the other side get's their shit sorted when your own side has its problems
That is totally misleading.
The most accurate "map" of the Globe is the computer based representation and that can locate places to within a few metres.
The accuracy of flat maps of the Globe depends on the area covered and the projection used.
But the various flat earth maps are inherently grossly in error. For example the ice-wall map grossly exaggerates east to west distance's.
Look at this:
Measurement | | Ice Wall | | Gleason's | | Garmin Nav |
West-East 30° Lat | | 8,700 km | | 8,700 km | | 3,700 km |
Cape Yk-Wils Prom | | 3,300 km | | 3,200 km | | 3,200 km |
As you can see the on both the "Ice Wall Map" and the "Gleason's Map" the
shape of Australia is grossly distorted, with the East-West distance on the "Ice Wall Map" and "Gleason Map" being 8,700 km compared to a more accurate distance of 3,700 km. The distances on the "Ice Wall Map" and "Gleason's Map" are estimated by comparing the lengths with the Equator to North Pole taken as 10,000 km.
The North-South distances agree very well, but E-W distances are grossly in error - All the distances have been rounded to the nearest 100 km.
I know the column labelled "Garmin" is correct as I have driven over much of that area (yes all the way from west to east, though not ON the 30° Lat). I have personally checked the maps, the car oddo and the "Garmin" (GPS) and all are in good agreement.
In any case, the errors are so great that
there is not the slightest chance of its being caused simply by "measuring error".
The whole point is that if the earth were flat, distances could be scaled (or easily calculated from lat/long) from the straight line lengths on the flat map.
But, on the
Globe, the distance scaled from a map will always have some error due to the projection distortion.
The
Azimuthal Equidistant Projection has the particular properties that all distances and directions from the centre of projection (the North Pole for the "UN map") are undistorted,
but most other distances and directions are distorted, some grossly so.
If you complain that these distances are from that "terrible"
Google Earth, here is an map surveyed before 1855.
Map of Australia 1855All I can do on that map is to measure distances the old way - measure distances from the map, but the same distances are close with 3659 km along the 30° parallel latitude.
The beauty of flat earth maps is that they can be anything you want them to be. No rules, no boring math to get in the way
An accurate map With correct angles and distances is very important for navigation.
You want an Ice wall? You got it
Or maybe not. That's OK too 
Dome? Or no dome?
Bipolar? Dual Earth? Australia a funny shape? Hey, no ones judging here
You are joking, I hope! "Australia a funny shape?"
I live in Australia, I know its size and I'm certainly judging maps that are grossly in error.
It's all up to you. So stop your bitching and nit picking and just pick one!!
So often various flat earthers make the ridiculous claim that soon everyone will "know" that the earth is flat.
That will never happen until there is an accurate flat earth map and
that is quite impossible because the known dimensions of the earth cannot fit on a flat surface,
Ask any competent geodetic surveyor!

Maybe that's why flat earth conspiratards regard all
geodetic surveyor! as
Freemasons

Sure, play around with flat earth ideas and maps, but neither work for the real world.
