In the traditional map vs territory parlance, the perfectly correct map is an identical copy of the terrain - needless to say, that's not very useful for most use cases, and we prefer a model that's known to be incorrect in many aspects e.g. it's shrunk at 1:24000 scale and has various types of detail intentionally omitted, making it less correct but more useful for the intended purpose.
