Showing how long it takes to move betwixt ii unlike points on a map tin endure difficult. The close mutual approach is in all likelihood to role an isochrone layer, which uses color to visualize journeying times geographically.
In the example above, from Mapbox, driving times from a selected scream for on the map are shown using unlike colors. In this instance at that topographic point is a continual gradation betwixt the unlike colors. However inwards lots of isochrone maps lines are drawn on the map connecting points which tin endure reached inwards the same move time. For instance lines mightiness endure used to present how far you lot tin move inwards 10, twenty & xxx infinitesimal increments.
Another approach to visualizing move fourth dimension on a map is to role a fourth dimension cartogram. In a fourth dimension cartogram geographic distance on the map is replaced past times a fourth dimension attribute such every bit move fourth dimension (Eric Fischer has posted a few time cartograms of San Francisco to Flickr). However the occupation amongst fourth dimension cartograms (as amongst all cartograms) is legibility. When you lot distort a map past times another variable apart from distance the map tin apace larn illegible, every bit users scrap to recognize the geography.
Nate Parrott has created an interactive fourth dimension cartogram to present NYC Subway Travel Time. If you lot click on a subway scheme station on Nate's map together with hence the subway scheme map automatically redraws itself hence that the distance to all stations is based on the journeying fourth dimension from your selected station. This interactive fourth dimension cartogram plant actually good every bit a visualization of journeying times together with it doesn't endure from the green problems of illegibility mutual to many fourth dimension cartograms.
There are a publish of reasons why the NYC Subway Travel Time Map plant hence well. To starting fourth dimension amongst users are already familiar amongst the concept that transit maps distort geography together with are non strictly geographically accurate. Users are too familiar amongst the role of colored lines to present the transit system's unlike lines. If you lot are already familiar amongst a line of piece of work together with its stations on the New York subway scheme map together with hence you lot volition withal endure able to selection it out on a distorted fourth dimension cartogram based on the line's color. Even if the NYC Subway Travel Time map confuses you lot together with hence you lot tin withal mouse-over a station on the map together with apace reorient yourself amongst the New York subway.
If you lot desire to brand your ain isochrone move fourth dimension maps together with hence you lot mightiness similar this How to Make a Travel Time Map post.
