Spatial Plane — Where Things Are¶

Purpose¶

The Spatial Plane is the platform’s understanding of physical space. It stores maps, floor plans, zones, and landmarks (Equator) and provides intelligent queries on top of that spatial data (Marie). Every application that needs to reason about location goes through this plane.

Services¶

Service	Responsibility	Detail
Equator	Spatial data management	Source of truth for maps, floor plans, zones, coordinates, landmarks
Marie	Spatial query engine	Proximity searches, coverage analysis, path clearance, zone-based lookups

Equator is the data; Marie is the intelligence on top of it. Developers interact with Marie for queries. Equator manages the underlying spatial model and is the write path for map data.

Named after Marie Tharp, the oceanographic cartographer who mapped the Mid-Atlantic Ridge.
