Re: [talk-ph] Bing or own aerial pictures...
This is brilliant, for sure, but it leads me to wonder about the idea of mapping using an automatic camera suspended (and therefore vertical) from a balloon or small aeroplane. So no need to rectify. I've read about some people doing this in France etc, but maybe this is a viable alternative to expensive aerial / satellite photography. And its portable, so its possible to take the plane/balloon to places where its needed and use it there. Thinking ... so we'd need - a model plane with remote control (and someone to fly it) - a GPS to record the altitude, lat and long at any given time. - a camera suspended in a sling which would allow it to be pointing towards gravity (or some way of measuring which angle it was pointing at) - some mechanism for taking photos every five seconds (say) and recording the time of the photo. Can't be too hard to figure out ... I'm guessing 1000 USD? Maybe we could even get a grant from the government for it?

Re: [talk-ph] Bing or own aerial pictures...
According to the wiki, not yet: http://wiki.openstreetmap.org/wiki/Bing But according to the people who knows, it's as good as approved. Let's just wait for the legal bleh.

Cool! I was about to ask you about your helicopter tours because of your recent edits, but Bing distracted me. Hehehe. Maybe you need a better camera set-up so you can get more vertical shots?
