A new kind of map: it’s about time – Points of interest
Isochrones get us a bit closer. With a starting point and a mode of travel, they examine the actual geometry of surrounding roads, to delineate an area based on how long it takes to get there. Areas within the same isochrone (Greek for “same time”) take a similar time to reach. Tendrils extend along fast-moving corridors, and squeeze to wrap around mountains, rivers, and other natural barriers.
A step further
But at the core, these maps still serve double duty in visualizing both space and time. Recently, we’ve been thinking of a visualization that cuts directly to the way in which people make decisions about where to go: what would a map look like if we swept the physical world away completely, in favor of the time needed to move around it?...

In this time map, we preserve the direction of each point, relative to the user. But the visual distance from that center point is determined by the time it takes to get there, whether driving, biking, or on foot.
By removing literal geography, we now have a map that more closely reflects the way we think about our environment: a cluster of restaurants “five minutes that way” versus “ten minutes the other.” We can watch our surroundings literally expand and contract with different means of travel. And only after choosing a destination do we think about roads, turns, and the specifics of how to get there.
