OpenStreetMap, or OSM, is behind the effort to produce a map more accurate than anything else on the market.
The Atlanta mapathon will take place this weekend, with around 200 volunteers armed with global positioning devices mapping the city.
"The way to think about it is as a really big mapping party," said OSM founder Steve Coast.
"We will have about 15-20 mapping stations throughout Atlanta and start by noting all the freeways and motorways, then the main roads, smaller roads and eventually go right down to the footpaths, bars and restaurants."
It needs some work, but the site is here: OpenStreetMap.org. I love the idea and I am delighted this is extending away from Atlanta and into one big crowdsourced interactive map. It will give Google Earth some competition at least.
