Merriam-Webster's definition of chronological:
of, relating to, or arranged in or according to the order of time
The spatially equivalent adjective I'm looking for would, ideally, be defined as:
of, relating to, or arranged in or according to the order in space
American Heritage's definition of chronology:
The arrangement of events in time.
The spatial noun would be defined as:
The arrangement of objects in space.
I've considered sequential and sequence, respectively. I understand them to refer to order in general and not specifically to spatial or temporal order; either context seems appropriate.
Likewise for serial and series.
