DATA & ATTRIBUTION

Where our routes, places, and maps come from.

Metroline Korea combines public Korean transport data, official English tourism records, and an open map layer. This page explains the role of each source, the transformations we make, and the limits travelers should understand.

01

Railway lines and station order

Route calculation begins with Ministry of Land, Infrastructure and Transport urban railway data distributed through Korea’s Public Data Portal. The source records identify regions, operators, lines, station sequence, and station names.

Additional official station-location files from Seoul Metro and the Korea Rail Network Authority extend geographic map coverage. When coordinates are not available for every stop, the site still presents the verified station order as a schematic route.

02

Visitor places

Nearby attractions, cultural sites, food-related places, addresses, and images are requested from the Korea Tourism Organization’s official English-language tourism API. Results are centered on the chosen station and currently use an approximate 1.5 km search radius.

A listing appearing near a station does not mean that it is open, free, accessible, or officially recommended by Metroline Korea. Travelers should confirm current hours, admission, reservations, and accessibility with the venue.

Map layer

The surrounding geographic map is provided by OpenStreetMap contributors. Metroline Korea draws route and network lines from station coordinates; these are visual guides between stations, not exact underground track geometry or walking directions.

04

How we transform the data

We normalize station and line names for an English-speaking audience, connect equivalent transfer stations, assign familiar line colors, and calculate a path through the station graph. Tourism records are filtered and presented near the station that was searched.

Romanization can vary between publishers. Where an established English station name is available, we prefer it; otherwise a consistent machine transformation may be used. Corrections are welcome through the Contact page.

05

Freshness and service limits

Checked-in data snapshots keep route planning usable during upstream outages. Live tourism requests may be cached briefly to reduce public API traffic. The site does not currently provide live arrivals, disruptions, crowding, fares, station opening hours, elevator status, or walking time.

Before travel, confirm time-sensitive information with the relevant transit operator, venue, or official tourism source.
