Roy Greenslade points to Chorley, an English town suffering from the lack of an official map. The local paper, the Chorley Guardian, used to produce one but it started a campaign to get the borough council to Give Us a Map.
But why not make a networked map? Start with Google Maps to satellite view of Chorley from above (who needs cartographers when we have satellites?). Then use a social mapping application like Platial to have local folks come in and fill in addresses and names; you don’t need everyone to do it, just that fabled 1 percent of nosy yet helpful neighbors. And they can add more than just names and addresses; they can review restaurants and warn you away from mean dogs. Or you can include dynamic information: report a pothole here. Google Maps will soon allow you find coupons for the local businesses. Then look at data applications like ChicagoCrime.org and layer on more information: arrests but also perhaps home prices. And, of course, because the UK has better mobile phones than we do, you’ll be able to see it all on your cell. While you’re at it, why not add on local tour podcasts (on your left, they’re having a nasty divorce….). By God, Chorley could end up with the best damned map on earth.
: And as a commenter points out, I should have included Up My Street.
And with GPS and a phone, people could leave voice or SMS annotations for any location in town.
LATER: More good ideas in the comments and here, too.
