US Map

Posted by Tom Layo on 21 June 2012 in English (English)

Many roads in the US are badly misaligned. I pick towns that have crooked streets and align them to Bing imagery. A follow up comparison with Transparent Map shows that the imagery is reliable. I think that an online list of all US towns that could be checked off after alignment might make this a more organized process. There could also be a ‘random town’ option if one did not know where to start.

Location: Ban Nong Praya Prom, Chiang Mai Province, 50130, Thailand

Typically, the is a good place to discuss such matters.

Although you would need with more people to maintain it. I suggest sending a mail to the US mailing list.

As well as the page Sanderd17 mentions you might also like to see the page about fixing TIGER alignment but yes, discussing it on the US mailing list is probably the best place to start.

Sounds like a good project for a beginner programmer :)

All you’d have to do is get the town list from somewhere (I’m sure you could find a good one if you asked around US people) and build a tiny web app that looks up a random town and redirects the user to .

Might be able to do it in just javascript.

Might even be able to do it as a bookmarklet (

Finding some areas you are operating in How do you ever stop, you see street after street, landuse after landuse, building after building that is wrong or missing
