Brazil

A Brazil runtime release based on the official IBGE 2022 Admin 0-4 hierarchy. District parentage is publisher-relationship-backed rather than advertised as a clip-safe geometric pyramid; bairros remain a separate neighborhood sidechain.

What this country release covers

One maintained release connects persistent place identity, display-ready map geometry, and exact query representations without treating them as interchangeable files.

Available geography families

A family is a recurring kind of geographic reference system. Only the selected complete hierarchy is the administrative spine; postal, electoral, health, watershed, and other systems remain independently versioned sidechains connected to it.

Available

Administrative hierarchy

The selected country hierarchy for administrative identity and parent lookup; the catalog separately declares whether its polygon levels are clip-safe nested geometry or relationship-backed authority layers.

Examples: states, provinces, counties, municipalities, census units
Available

Neighborhood areas

Authority- or publisher-defined neighborhoods and submunicipal named areas that are not promoted into the administrative spine or treated as city/place identities.

Examples: bairros, neighborhood polygons, submunicipal named areas

Local download packages

Lite contains identities and crosswalks, Display adds simplified map geometry, and Detail adds the highest-resolution maintained geometry. A package appears as downloadable only after artifact and public-reachability QA passes.

Release QA

  • Admin 0-4 uses held official IBGE 2022 geometry with official identities and parent relationships.
  • Admin 3 district parentage is relationship-backed across the independently published municipality and Census-mesh seam and is not advertised as clip-safe nesting.
  • Admin 4 subdistricts remain children of official districts.
  • Bairros remain a municipality-scoped neighborhood sidechain and never become Admin 5.
  • No city or municipal-seat point source is synthesized from administrative polygons.
