United States geographic data sources

Source notes for the United States location and transit directory on Zeppik. Last reviewed: 25 October 2026.

Places and states

Names, state relationships and representative coordinates are derived from public-domain U.S. Census Bureau Gazetteer and TIGER geographic data. Coverage is the 50 states and the District of Columbia. Census-designated places are statistical areas, not necessarily incorporated cities. Coordinates represent source geographic points, not street addresses or exact downtown locations. State coordinates identify the capital city rather than the state centroid.

Popular-city selection uses the Census Bureau's 1 July 2025 incorporated-place population estimates; it is not a ranking of metropolitan areas.

New York City transit

Data provided by the Metropolitan Transportation Authority (MTA), supplemented by MTA station and station-complex records published through New York State Open Data. Zeppik is independent and is not endorsed by the MTA or New York State.

The directory records 424 NYC Subway physical station complexes and 21 Staten Island Railway stations. Interchange platforms are grouped using official complex identifiers instead of being duplicated for each route. Repeated station names may include route identifiers to distinguish locations. The subway system's gray display swatch is a directory grouping color, not an official subway route color. Staten Island Railway is listed separately.

Source schedule coverage was checked for 24–30 October 2026. This is a location directory, not real-time service information, a journey planner or a promise that a station is currently open. Check the operator for service changes and accessibility. The United States transit directory remains incomplete outside the systems specifically identified here.

Additional transit source credits

The following records are staged in the directory. Catalog records do not imply that every city page is publicly available or that nationwide metro coverage is complete.

• Los Angeles Metro B/D: California Department of Transportation (Caltrans), California Transit Stops, Creative Commons Attribution as stated in the source catalog (version unspecified there). Nineteen physical stations are partitioned between Los Angeles (18) and Beverly Hills (1). Source stop names and representative points are adapted to city-based records; interchange routes are not duplicated. LA light-rail lines are excluded.
• MBTA Red, Orange and Blue: MassGIS (Bureau of Geographic Information), Commonwealth of Massachusetts EOTSS, MBTA Rapid Transit data (public-domain geographic data), with current-service verification using MassDOT/MBTA GTFS under the MassDOT developer data license. Fifty-two complexes are grouped by Census city; Green Line, Mattapan and Silver Line are excluded. Zeppik is not endorsed by MassDOT, MBTA or MassGIS.
• Baltimore Metro SubwayLink: State of Maryland, MD iMAP and Maryland Transit Administration, Maryland transit station source. Source metadata permits free distribution with attribution. Fourteen stations are mapped to Baltimore, Lochearn and Owings Mills; postal-locality labels are not substituted for Census polygon matches.
• Cleveland Red Line: Greater Cleveland Regional Transit Authority, GCRTA developer data and terms. Eighteen physical stations are grouped from GTFS station/platform records and matched to Cleveland or East Cleveland. Source names are retained, with explicitly reconciled Little Italy platform grouping. Zeppik is independent and is not endorsed by GCRTA.
• MARTA: Atlanta Regional Commission / Metropolitan Atlanta Rapid Transit Authority, MARTA Rail Stations dataset, Creative Commons Attribution 4.0. Thirty-six station records are adapted to the city-based catalog, matched to Census polygons and reconciled with the current operator roster, including the SEC District rename. Kensington and Indian Creek, two further source stations, remain outside the imported place polygons and are held rather than assigned to a nearby city. No operator endorsement is implied.
• Washington Metro — District of Columbia subset: Washington Metropolitan Area Transit Authority / District of Columbia, Metro Stations in DC, Creative Commons Attribution 4.0. Forty station records are normalized for the Washington city catalog. The roster was checked against the current official WMATA system map on 25 October 2026. This DC-only subset is not the full Metro network and does not certify real-time service.
• Miami Metrorail — City of Miami subset: City of Miami, Department of Innovation and Technology, GIS Team; Miami-Dade County, Information Technology Department, Metrorail station data, Creative Commons Attribution 4.0. Ten stations are matched to Census city polygons; source capitalization is normalized and Civic Center is displayed under its current name, UHealth | Jackson. The current operator-linked map was checked on 25 October 2026. This subset is not the full 23-station system.
• BART: California Department of Transportation (Caltrans), California Transit Stops, Creative Commons Attribution as stated in the catalog (version unspecified). Source platforms are grouped into physical stations and checked against the official BART station roster. The staged city-matched heavy-rail subset contains 45 stations across 24 Census places. Colma and San Francisco International Airport are held because their source points fall outside the imported Census-place polygons. The two eBART hybrid stations and Oakland Airport connector are excluded. These limits do not describe the entire BART network.

System-wide gray swatches identify directory groupings and are not official route colors. Source coordinates and original identifiers remain in the provenance ledger. Grouping, city matching and current-name reconciliation are adaptations made for this directory.

Changes made for the directory

Source records have been matched to Census places, grouped into physical station complexes where supported, and adapted to Zeppik's city and station-name fields. Station coordinates and source identifiers are retained in the provenance ledger; the current station editor does not display those fields. Unmatched stations are not assigned to the nearest city by guesswork.
