How Fourth Dimension Tin Curvature Space
Showing how long it takes to move betwixt 2 dissimilar points on a map tin live on difficult. The some mutual approach is likely to role an isochrone layer, which uses color to visualize journeying times geographically.
In the example above, from Mapbox, driving times from a selected indicate on the map are shown using dissimilar colors. In this instance at that topographic point is a continual gradation betwixt the dissimilar colors. However inwards lots of isochrone maps lines are drawn on the map connecting points which tin live on reached inwards the same move time. For instance lines powerfulness live on used to exhibit how far y'all tin move inwards 10, twenty & thirty 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 equally 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 y'all distort a map past times another variable apart from distance the map tin apace cash inwards one's chips illegible, equally users handle to recognize the geography.
Nate Parrott has created an interactive fourth dimension cartogram to exhibit NYC Subway Travel Time. If y'all click on a underground station on Nate's map therefore the underground map automatically redraws itself therefore that the distance to all stations is based on the journeying fourth dimension from your selected station. This interactive fourth dimension cartogram industrial plant actually good equally a visualization of journeying times too it doesn't endure from the green problems of illegibility mutual to many fourth dimension cartograms.
There are a discover of reasons why the NYC Subway Travel Time Map industrial plant therefore well. To outset amongst users are already familiar amongst the concept that transit maps distort geography too are non strictly geographically accurate. Users are likewise familiar amongst the role of colored lines to exhibit the transit system's dissimilar lines. If y'all are already familiar amongst a occupation too its stations on the New York underground map therefore y'all volition all the same live on 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 y'all therefore y'all tin all the same mouse-over a station on the map too apace reorient yourself amongst the New York subway.
If y'all desire to brand your ain isochrone move fourth dimension maps therefore y'all powerfulness similar this How to Make a Travel Time Map post.
