Friends of friends have done high-altitude balloon photography using weather balloons.  This isn't quite the same thing as what you are planning, but I will try to find their contact details.  One difficulty of using such photos for mapping, it seems to me, will be determining the downward angle at which the photos were taken, so as to calculate the perspective.
