𝗠𝗲𝘁𝗿𝗼𝗰𝗵𝗿𝗼𝗻𝗲𝘀: 𝗦𝗰𝗵𝗲𝗺𝗮𝘁𝗶𝗰 𝗜𝘀𝗼𝗰𝗵𝗿𝗼𝗻𝗲𝘀 𝗳𝗼𝗿 𝗦𝗰𝗵𝗲𝗺𝗮𝘁𝗶𝗰 𝗠𝗲𝘁𝗿𝗼 𝗠𝗮𝗽𝘀 Maps of transportation networks often depict the area that is reachable within a certain amount of time from a certain start point. Usually, the boundary of this area is drawn as a line, which is called isochrone. In an article recently published in The Cartographic Journal, we present an algorithm that generates schematic isochrones for schematic network maps. Our algorithm generates isochrone maps that correctly represent travel times while being much easier to read than geographically accurate isochrone maps. Our article is part of a special issue that celebrates the 90th anniversary of Henry Beck's famous schematic map of the London Underground. https://lnkd.in/eDGr3yr6 #Isochrones #SchematicMaps #Algorithms #HenryBeck #Research
