Why OpenStreetMap is brilliant

Wednesday, July 29th, 2009

We all know about Google Maps and how brilliant it is. It’s gone from simple online mapping website, to an essential tool for mobile phones, complete with satellite photography, your friend’s location (Latitude) and, of course, the extremely groovy Street View.

But it’s not the only free mapping tool around, and not even the best, as I’ve been finding out over the past few months. The OpenStreetmap is a venture, started in 2004 by Steve Coast, similar to Wikipedia, only with maps.

His idea was that rather than rely on corporations with big budgets and teams of cartographers, or national institutions to generation mapping data, he would get the internet community to build up its own using GPS traces and donated satellite imagery.

I remember looking at it three years ago and being distinctly unimpressed at the level of detail.

And as time goes on, its accuracy and usefulness can only increase.
