I’m always fascinated to see old mapping techniques replicated in modern mapping software. For an example, see Robin Hawkes’s tutorial on creating hachure maps in QGIS. Which Patrick McGranahan followed to create this map of San Marino.
San Marino is the fifth smallest country in the world, but it’s large enough to have a bus network, for which Jug Cerovic has created a map. It’s a network diagram that includes not only San Marino’s domestic bus routes, but its connecting bus line to Rimini, Italy (where you can connect to/from trains and planes) and its funicular railway (Wikipedia: Transport in San Marino). It’s also something we almost never see in a transit map: an oblique view. Adding perspective makes total sense: with San Marino and its hills in the foreground and the Adriatic Sea in the distance, we get more detail where it’s needed and connections to the rest of the world in the distance.
