Bing has transformed the mapping process no doubt, but there are still many areas that would benefit from high res imagery ( much of Africa for one - Question why is Abuja, capital of the most populated country in Africa still a blur ).
Team Black Sheep seem to have an answer with their amazing aircraft and incredible videos : http://www.vimeo.com/24417184
Still ,if I was to take up a new hobby like this I doubt I would have a dime or a second left for mapping!
Off to Nigeria in August to write my thesis -( I am sure I can spin in mapping with developing small business networks somehow ! ) - with a pocket full of i Blue 747s to see what I can generate while I am there - but wow, do I want one of those stunt planes ( strictly for mapping purposes of course! )
