Creating a Map Based on Distances Between Cities
October 29, 2009 7:03 PM Subscribe
Mapping question: I have a list of (imaginary) cities. I also know each city's as-the-crow-flies distance from every other
city on the list. Based on this data alone, I would like to create a (hypothetical) map that shows all of these cities in their proper locations. I recognize that that the map's "rotation" would be arbitrary based on where & how you start plotting, but it seems that you should be able to plot out the relationships between cities properly. Is there software that can help me do this?

To be a little more concrete, imagine that you have a mileage chart similar to this one
. (That chart contains driving distances, but let's assume we have as-the-crow-flies distances instead.) If you pick an arbitrary starting point for one city, you can then plot out where every other city belongs, because you know how far each city is supposed to be from all the other
I can envision at least one simple way to do this manually if you have just a handful of cities. But if you have a lot of cities, it becomes harder and harder. So I'd love to know if there is software that can calculate and draw such a map automatically. (Note: Using latitude/longitude is not an option - the scenario only involves knowing as-the-crow-flies distances between imaginary cities.) Thanks!
