This page contains some city-scale maps I created in my spare time. Please see each map for data sources.
Subway stations with the most entrances are People's Square Station (18 entrances) and Xujiahui Station (19 entrances), as shown in the map. Presumably, these are two city centers of Shanghai.
Some data points' latitudes and longitudes may be inaccurate. Are there listings inside the Central Park?
"The BeltLine is a former railway corridor (rail-to-trail) around the core of Atlanta, Georgia under development in stages as a multi-use trail. Some portions are already complete, while others are still in a rough state but hikeable. Using existing rail track easements, the Beltline was designed to improve transportation, add green space and promote redevelopment. There are longer term visions for streetcar or light rail lines along all or part of the corridor." From Wikipedia.
