Mapping the Fourth Dimension

Good to see that Yahoo is letting OpenStreetMap use its aerial imagery to speed up the process of free map creation.

Of course, we still need to get all those street names and features. GPS traces are by no means dead - think of the new housing estates and areas without imagery. But instead of cycling down every road you should be able to just pass lots of them at either end to get the names. Or just from memory.

Where does this bring us to? Well the ‘big map companies’ use expensive cars and expensive aircraft with expensive cameras and expensive GPS units to create maps. Maybe our GPS units are cheaper and less accurate, but does it matter? I think not. We now have all the pieces of the puzzle and we’re putting out great maps for Free using Free tools.

But I was even more impressed to see that OpenStreetMap has already mapped some of the future too: take a look at the entries here for March 2007.
