Well Link's Awakening took place inside a whale's dream so you're gonna have difficulties plotting that.Yes, there's an actual geographical world that all of the games take place in.
The exact geographical location (in terms of Link's physical position) is somewhere between Holodrum, Labrynna, and Hyrule. Popular theory is that it's between east and west greater hyrule. There's a theory that someone posted which I particularly like, that speculates that Koholint (the island in Link's Awakening) was actually "sucked up" and would be east greater hyrule. There's a lot pointing to it, but nothing officially confirmed. Also, Koholint itself, being a dream, is based on LTTP's hyrule. The dev reason was due to it originally going to be a remake, but then it became it's own game.
