In cartography, it's called 'generalization': the smaller the scale,
the less detail you can show.
There are practical problems associated with the full scale renderings
you seem to desire e.g.
"...What do you consider the largest map that would be really useful?"
"About a six inches to a mile."
"Only six inches!" exclaimed Mein Herr. We very soon got to six yards
to the mile. Then we tried a hundred yards to the mile. And then came
the grandest idea of all! We actually made a map of the country, on the
scale of a mile to the mile!"
"Have you used it much?" I inquired.
"It has never been spread out, yet," said Mien Herr: "the farmers
objected: they said it would cover the whole country, and shut out the
sunlight! So we use the country itself, as its own map, and I assure
you it does nearly as well."
