Although subway maps more or less correctly show the different train stations and routes, they are not exactly a perfect representation of the actual geography of the area.
Benjamin M. Schmidt, an assistant professor of history at Northeastern University in Boston and a core faculty member at the NuLab for Texts, Maps, and Networks, overlaid the subway maps of Boston, New York, and Washington onto the actual maps of these cities.
The Corrected Subway Maps show how close (or far) the transit maps are to the real topography of the city. According to Schmidt’s website, the corrected maps represent the “tension between two different ways of representing the same urban spaces.”
Schmidt created the maps using the free and open source geographical information system application QGIS, the mobile-friendly map library Leaflet, command-line GDAL tools, and using data from transit authorities, and tiles from Open Street Map.
