NYC Who's On First Counties

Knowledge resource

A governed public view of Who's On First as a boundary-data publisher — the five exact current county gazetteer records used by NYC Boundaries. For how these records compare against DCP, the Census Bureau, OpenStreetMap, and other independently governed sources, see NYC Boundaries.

Dataset

This page governs five county records from the whosonfirst-data-admin-us repository, pinned at commit c4e4f9b. A sixth record — the New York locality (WOF ID 85977539) — supplies five-county hierarchy context but is not counted as a boundary assertion; it is not represented in the measurements table below.

Records

All five governed county records, as published by Who's On First. Each record's default geometry is Quattroshapes, sourced from the U.S. Census Bureau (qs:source), not an independently surveyed WOF geometry.

Each record's WOF geom:area_square_m value, derived with Shapely from its Census-sourced Quattroshapes geometry, is retained in the raw fixture: Who's On First county representations fixture. It is not a land-only or independent measurement, so it is not directly comparable with the DCP/Census land-area table on NYC Boundaries.

Rights and attribution

Who's On First's own record structure is released under CC0 1.0 (public domain dedication). The default geometry each of these five records carries is Quattroshapes under CC BY 2.0 attribution terms, and each record identifies the U.S. Census Bureau as its geometry source (qs:source).

Validation and provenance

Each record's identity, Census GEOID/HASC concordance, and source-owned wof:lastmodified value were retrieved directly from the pinned repository commit and cross-checked against the governed assertion records via exact git blob SHA; this page does not independently verify the underlying Quattroshapes geometry. For independent cross-source verification of these records, see NYC Boundaries.

Scope
Who's On First's own published record identity, hierarchy, and concordance values, as retrieved from the pinned repository commit. Confidence is High because the record structure and concordances are stable and precisely versioned, even though the default geometry itself is a Census-sourced derivative, not independent.

Limitations

The five governed records are the exact versions retrieved at the pinned commit c4e4f9b, not a live feed. Each record's default geometry is Quattroshapes, sourced from the U.S. Census Bureau — the same provenance cluster as this pack's Census Gazetteer records, not independent corroboration. The New York locality record's five-county hierarchy is retained as context only and is not counted as a boundary assertion. This page presents Who's On First's own published values; it is not the place to compare Who's On First against other sources — that comparison lives on NYC Boundaries.
