Of the People, By the People, For the People
I'm rather slow in this one, but it's such a good example of how everyone gains from public collaboration - including Google, whose CTO of Google Earth, Michael Jones, is speaking here:This is Hyderabad, and if you see the dark areas, those correspond to roads in low detail. If you zoom in, you'll see the roads, and if you expand a little bit, you'll see both roads and labelled places... there's graveyards, and some roads and so forth.
Now, everything you see here was created by people in Hyderabad. We have a pilot program running in India. We've done about 50 cities now, in their completeness, with driving directions and everything - completely done by having locals use some software we haven't released publicly to draw their city on top of our photo imagery.
This is the future, people - your future (though I do wonder about the map data copyright in these situations).
