if the answer you're going to give is the bing map then you're simply wrong.
I would hate to live in a world where, after thousands and thousands of years, we were still unable to make an accurate map of the world. This is where our views differ.
We do have extremely accurate maps and their accuracy is dependent upon the projection from a globe using globe coordinates systems and distances. One can certainly create a map that is very accurate on a much, much smaller scale, for the sake of argument let's say 100km x 100km, without having to get into the globe projection business. But at scales greater than that accuracy will begin to subside. e.g., State Plane Maps.
"(State Plane Maps)
By using the Cartesian coordinate system's simple XY coordinates, "plane surveying" methods can be used, speeding up and simplifying calculations. Second, the system is highly accurate within each zone (error less than 1:10,000). Outside a specific state plane zone accuracy rapidly declines, thus the system is not useful for regional or national mapping."
But we are talking about World maps here. A World map is not a 'model', it is a representation of a model. In the case of all these maps, Bing, Google, AEP, etc., they are all representations, more specifically, 'projections' of the World model. And the 'projection' representations onto a flat map surface is that of a Globe 'model'. For example, Bing, like many other maps uses the very common Mercator Globe Projection, accurate for distances but distortion in size:
Bing: Greenland is massive! Bigger than Africa. It is not in reality.
The overall point is that using a map as
the model for the world is going at it backwards as maps are derived from the model, not the other way around. At least in 2020. For globe believers the job has already been done, the model is a globe. And if you have a globe, check it out, it's extremely accurate and without distortion, if not a little unwieldy to take as your navigation tool on your next road trip.
If you want a flat earth 'model', not a map, but a model, for a flat earth, seemingly a model-to-map should be dead simple as there would technically be none of this globe projection business that distorts things. As well a flat earth model would need to be as accurate as a globe without distortion just like a globe doesn't possess distortion. An FE model-to-map should be 1-to-1.
So think model, not map. The map should be easy once an FE model exists.
