Pittsburgh is on the beer map -- that is, it's part of the Internet "Beer Mapping Project."

Just click to beermapping.com/maps/pittsburghbeer.html, and you'll see the familiar three rivers and surroundings, with marks pointing you to brewpubs, breweries, beer bars and beer stores.

This is the creation of Jonathan Surratt, who's studying e-commerce at DePaul University in Chicago. The self-described "beer nerd" this past October started this project -- to map regional beer landmarks he finds at beerme.com and other sites -- as "something that was fun for me to do in my spare time."

Then in January he got mentioned on National Public Radio and got slammed with e-mailed requests and submissions from all over the country.

So far he's posted maps for 18 cities, as well as maps showing breweries and brewpubs in his native North Carolina and in the United States. By clicking on the "pins," or markers, you can get a place's address, contact info and directions. Or you can use a brewery and brewpub lookup function to find that information and the points on the map (and link to details on other sites).

This type of mapping is based on the Google Maps API, an open programming code that lots of Web developers are playing with. Using various technologies to merge data to Google maps results in "mashups" that help users easily plot everything from pizza joints to sex offenders.

Mr. Surrat says the automated plotting he uses may be off by a few hundred yards. Users can send corrections and submissions to a new submissions page at beermapping.com/location-submission/.

"Feel free to either e-mail me or submit any of the places you're aware of that I've missed," he invites. "Hopefully it's fairly accurate, but like I said, I don't have the Pittsburgh experience to test it myself."
