Im working on a project that requires georeferencing, so this post caught my eye. Grass GIS (open source GIS) has a georeferencer utility and MapAnalyst (http://mapanalyst.cartography.ch/index.html) can calculate distortion. A great idea with the balloons!

Roof material can be seen, and from some of the sideways images (like <a href="http://www.flickr.com/photos/jeffreywarren/4276485077/" rel="nofollow">this one</a>; see more at the <a href="http://www.flickr.com/photos/tags/grassrootsmapping" rel="nofollow">Flickr feed</a>) we can definitely make out wood/brick/plastic. But I'm hoping we can run around with the kids and do a quick survey of building materials anyways.
