Culture Or Region
Area Context
Default: Hierarchy. Coordinates: permitted when explicitly sourced. Hierarchy: supported.
ATLAS / FOUNDATION
Place before pin.
The Atlas treats geography as evidence: a coordinate has precision, a place has containment, and some entities should never be reduced to a point at all.
Spatial reasoning map
One world, six complementary ways to think.
Start with the question you have, then move between lenses. Each route changes the view, not the evidence contract.
01 / Coordinate field
A map-ready point layer without pretending the map is the data.
02 / Non-map equivalent
Accessible geographic hierarchy
The hierarchy below is the primary semantic structure. It remains usable without a map, JavaScript, pointer input, or a tile service.

04 / Placeability
Every entity kind gets an explicit spatial role.

05 / Safety
Coordinates never become public merely because they exist.
Default: restricted
Unreviewed coordinate-bearing records default to restricted exposure.
No inherited pin
A child without its own coordinate keeps hierarchy context; it never steals a parent coordinate.
Equivalent discovery
The hierarchy and ledger preserve core Atlas information for non-map use.
06 / Cross-universe companion
Trace real places across multiple ICU universes.
The foundation above proves coordinate uncertainty and non-map equivalents with synthetic fixtures. Open the Cross-Universe Atlas of Place and Environment for a documentary companion containing eight source-backed place contexts and 24 links into existing ICU records.
