John Tierney on the Power of Mapping

A picture is worth a thousand words; the right map, maybe more

As I mentioned in introducing my wife Deb's very popular post on "What We Mean When We Say Hello," she and I, along with John Tierney, are all doing reports for our American Futures project, and they all show up at that project page. But now John and Deb will be doing their installments on their respective author pages (his, and hers).

John has just put up a fascinating post on "The Power of Mapping." It explains some of the ways we're trying to use Esri maps and other visual tools in both planning and chronicling our travels.

Here is a screenshot of one of John's interactive maps: it shows high-tech manufacturing firms across some Southeastern states. You can click on each of the dots for information about the company, zoom in and out for closer-up or broader views, pan around, and so on. Also, as John explains, you can layer these results over other variables to see patterns. This is the Greenville-Greer-Spartanburg region of upstate South Carolina.

For more, I turn you over to John Tierney.
