Showing how long it takes to go betwixt 2 unlike points on a map tin hold upwards difficult. The almost mutual approach is in all likelihood to purpose an isochrone layer, which uses color to visualize journeying times geographically.
In the example above, from Mapbox, driving times from a selected betoken on the map are shown using unlike colors. In this instance in that location is a continual gradation betwixt the unlike colors. However inwards lots of isochrone maps lines are drawn on the map connecting points which tin hold upwards reached inwards the same go time. For instance lines mightiness hold upwards used to demo how far you lot tin go inwards 10, xx & thirty infinitesimal increments.
Another approach to visualizing go fourth dimension on a map is to purpose 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 go 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 rapidly larn out illegible, every bit users combat to recognize the geography.
Nate Parrott has created an interactive fourth dimension cartogram to demo NYC Subway Travel Time. If you lot click on a underground station on Nate's map together with thus the underground map automatically redraws itself thus 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 park problems of illegibility mutual to many fourth dimension cartograms.
There are a pose out of reasons why the NYC Subway Travel Time Map plant thus well. To commencement amongst users are already familiar amongst the concept that transit maps distort geography together with are non strictly geographically accurate. Users are besides familiar amongst the purpose of colored lines to demo the transit system's unlike lines. If you lot are already familiar amongst a business together with its stations on the New York underground map together with thus you lot volition all the same hold upwards able to alternative 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 thus you lot tin all the same mouse-over a station on the map together with rapidly reorient yourself amongst the New York subway.
If you lot desire to brand your ain isochrone go fourth dimension maps together with thus you lot mightiness similar this How to Make a Travel Time Map post.
