The Elastic Railway Map

Travel fourth dimension is oft represented using an isochrone map. On an isochrone map lines tin live on drawn to connect points to present areas which tin live on reached from ane starting indicate inwards an equal go time.


Influenza A virus subtype H5N1 printed isochrone map is commonly restricted to visualizing the go times from ane specific location. For illustration Francis Galton's Iscochronic Passage Chart, the get-go known isochrone map, shows the go times from London to different parts of the world. The map visualizes how many days it would accept to go from London to different locations across the globe inwards 1881.


Interactive isochrone maps receive got the wages of beingness able to present go fourth dimension layers for to a greater extent than than ane location. They tin allow users to indicate to a place on the map as well as redraw the isochrone lines on the fly. For illustration TravelTime allows you lot to click on a map to persuasion the go times from the selected location. Therefore, dissimilar printed isochrone maps, interactive isochrone maps tin present go times from to a greater extent than than ane starting point.

Interactive go fourth dimension maps are soundless still restricted inwards that they tin solely actually present ane or 2 isochrone layers at whatever ane time. Once you lot start adding to a greater extent than than a few starting points to a map the overlapping ischrone layers driblet dead difficult to read. If you lot desire to present go times from to a greater extent than than ane place at the same fourth dimension as well as on the same map so you lot powerfulness desire to purpose a go fourth dimension cartogram.


On Time Everytime is an interesting interactive map that attempts to present the go fourth dimension betwixt every Dutch station at the same time. It does this past times moving stations closer or farther away from each other on the map based on the go fourth dimension betwixt each station. It thus takes the approach of a cartogram inwards visualizing go times, distorting geographical distance based on the fourth dimension it takes to go betwixt locations.

The On Time Everytime interactive map visualizes the movement of all trains on the Dutch railway network over the course of report of ane hateful solar daytime - Dec 14th 2018. It thus shows the go times betwixt the different stations at all times over the course of report of a unmarried day.

Because roughly trains are faster than others the go times betwixt private stations constantly changes depending on the speed of the develop traveling betwixt the 2 stations. On Time Everytime overcomes this employment past times moving the locations of the stations closer together or farther apart on the wing depending on the electrical current train's journeying time. It thus takes an interactive cartogram approach to visualizing go time, distorting the geography of the map on the wing based on the speed of the trains currently shown on the map.


Nate Parrott has likewise created an interactive go fourth dimension cartogram to present how long it takes to go betwixt stations on a world transit network. If you lot click on a station on his NYC Subway Travel Time map so the New York underground map automatically redraws itself so that the distance to all stations represents the journeying fourth dimension from your selected station.

Users of the map are already familiar alongside the concept that transit maps distort geography as well as are non strictly geographically accurate. Therefore this interactive go fourth dimension cartogram plant actually good every bit a visualization of journeying times every bit it doesn't endure unduly from the commons problems of illegibility mutual to many fourth dimension cartograms.

Users are likewise familiar alongside the purpose of colored lines to present the transit system's different lines. If you lot are already familiar alongside a line of piece of work as well as its stations on the New York underground map so you lot volition soundless live on able to selection it out on a distorted fourth dimension cartogram based on the line's color. Even if you lot are confused past times the NYC Subway Travel Time map you lot tin soundless mouse-over a station on the map as well as rapidly reorient yourself based on station names.
