Mapping Systems final

Near is not the same as accessible.

After Six compares geographic proximity with a modeled cultural journey shaped by departure time, subway travel, walking, price, opening hours, step-free proximity, and personal interests.

How a route is made

selected startnearest stationGTFS station-line graphbest of 8 destination stations

Dijkstra's algorithm finds the lowest-time path through station-line states. Edges represent scheduled travel or transfers. Blue lines show subway movement; gray dotted lines request pedestrian street geometry from the OpenStreetMap routing service when a venue is selected.

What is verified

Every mapped point has a screened public address, description, official website, current-program page, route, and source-backed visit information. Fixed weekly hours, recorded closure periods, and date-specific cinema showtimes are evaluated at the modeled arrival time.

What remains uncertain

The model does not include buses, live delays, elevator outages, every one-off event, last-minute sellouts, exact pedestrian geometry, station-specific transfer paths, or whether a cultural space feels welcoming to a particular visitor.
