Friends, today I offer you a small, eclectic, briefly narrated selection of maps. We’ll start close to home with Austin radio, head east to an impressive cartographic undertaking in Boston, and finish with the connected universe as seen in Flickr and Twitter.

KUT is the local public radio station in Austin. This map shows its transmitter coverage at 70 dBu, and also the rugged landscape of the Central Texas hill country. More here.

Boy, Boston has some ambition. The creators of Bostonography have accumulated a wealth of data to map their city in creative graphics, including bus speed, cemeteries, furniture districts, street name origins (look, it’s awesome!), baseball radio (stations broadcasting Yankees/blue and Red Sox/red games), and autumn leaves. The last two are shown here.

Finally, Eric Fischer – who mapped tourist and resident photos using Flickr tags – has done it again with “See something or say something,” showing us what people are photographing and talking about on Twitter and Flickr. Here’s his Tokyo map, which looks like a small electronic galaxy to me. Check out Mr. Fischer’s own Flickr photostream to see more cities, including Philly and NYC, and a heap of other cool stuff.
