Allocentric frame of reference is defined as

In orientation and mobility, allocentric refers to how we understand space by describing where objects or places are in relation to each other, not in relation to ourselves. It’s like having a map in your head where the position of one item is defined relative to another—“the library is north of the park,” or “the cafe is east of the bank.” This allows you to reason about an environment independently of your current location or orientation. That’s why the best description is: relating the location of objects/places to one another. It’s not about describing space relative to the observer (which would be egocentric), nor is it limited to compass directions alone, and while landmarks can be part of it, simply using landmarks from memory doesn’t define the frame of reference itself.
