# Turn curated US dining neighborhoods — first edition

Prepared 2026-09-17. 36 polygon features across 22 cities, selected from 40 candidates in 25 cities.

## Files
- foodie_neighborhoods.shp/.shx/.dbf/.prj/.cpg: ESRI Shapefile. Keep these five files together.
- foodie_neighborhoods.geojson: equivalent boundaries with full source identifiers, source geometry names, and boundary caveats. Preferred for Turn.
- catalog.csv: selection source for every exported area.
- boundary_gaps.csv: 4 curated areas lacking a verified matching polygon; no fabricated boundary is supplied.
- curation.csv: all 40 candidates, including the gaps. City coordinates are matching aids, not neighborhood centroids.

## Meaning and selection
This is a curated dining-discovery seed dataset, not an exhaustive inventory of every hip neighborhood in America or a ranked list. Each candidate has a destination-organization or editorial dining source. No demographic, race, age, income, popularity score, or restaurant-count inference is used. Source pages were checked during this task; sources vary in publication date and are not proof that individual restaurants are still open.

## Geometry
Coordinates use WGS 84 longitude/latitude (EPSG:4326 / GeoJSON CRS84 axis order). Use spatial indexes for restaurant point-in-polygon lookup. Use GeoJSON for complete provenance; shapefile field names and text lengths are limited.

Overture Maps release 2026-08-19.0 supplied 9 features. Who's On First supplied 27 features, matched using its 2025-04-07 US index and fetched as individual GeoJSON records on 2026-09-17. A data download date does not make an older boundary newly surveyed.

Matching required a normalized exact name or documented alias plus proximity within 40 km of the listed city; state was checked when available. Same-area source pieces were unioned. Invalid geometries were repaired and the exported polygons validated and reopened. Existing polygons were used rather than bounding rectangles or radius buffers. Broader city or district polygons were not silently substituted for missing neighborhood boundaries.

Neighborhood definitions are informal and may overlap. These are neighborhood footprints, not footprints restricted to restaurants. East Passyunk uses East Passyunk Crossing, which is narrower than the full dining corridor, and is marked partial_area in GeoJSON. WOF records with unknown current status are marked currency_unconfirmed. Review these before automatic production assignment. Restaurant owners should be able to correct their dining-area assignment.

## Boundary gaps
RiNo / River North Art District and Lower Highland in Denver; Inman Park in Atlanta; The Grove in St. Louis. They remain in the candidate CSV and need a city/district polygon source. A surrounding parent neighborhood would not be an exact substitute.
