Geos Core Data Product

The Geos CDP defines the geographic boundaries used by all other CDPs. It provides region definitions, county boundaries, and spatial reference data.

Regions

Replica organizes data into hierarchical geographic regions:

Type	Examples	Purpose
Nationwide	usa	Full US coverage
Megaregion	california_nevada, mid_atlantic, great_lakes	Regional builds for Places pipeline
Test region	mini_kc, mini_nor_cal	Fast iteration and CI testing

Key Tables

model-159019.geos.region

The primary region boundary table. Each row is a region with: - id — unique region identifier (format: replica:region:{name}:{hash}:region) - geom — boundary geometry (POLYGON/MULTIPOLYGON)

Used extensively for spatial filtering across all CDPs:

SELECT data.*
FROM `model-159019.{dataset}.{table}` AS data
JOIN `model-159019.geos.region` AS region
  ON region.id = '{region_id}'
  AND ST_COVERS(region.geom, data.geom)
