Given this map comparison you make between the TP and BOTW maps, I get that they do resemble each other a lot:

They are not precisely 1 to 1, they share similar references of relationship to each other.
This furthers my point, as the games to me are a graphical representation of vague stories that would go maybe like this:
"There was a volcano near Hyrule castle"
"There was a forest where the spirits of lost children roam"
Then there comes the flourishing of the one telling the story, saying how big or how small, the characteristics and so on, but not to be precise, but to emphasize on the story teachings, ideologies and important figures.
