Originally, the habitation space on the Earth was piecewise, it was a world of distributed locations.
Navigation made it more connected.
The degree of geospace connectivity significantly increased with the appearence of aviation. Communication systems added the final touch - geospace became closed, holistic.
The geospace development stages can only be roughly identified to an accuracy of centuries.

The space not only unclosed, it became infinite for humans.
