comment automating roof orientation detection from satellite imagery
@Thad it's useful to know that I would actually need to use 3D data in order to automate this, something I can bring up with respect to funding.

@elrobis it is a small area but I'll have to do more in the future. I would also like to expand my knowledge of how to approach this challenge.

@whuber Yes, I still need to identify half of them and for that I would like to automate. So far I've digitised the relevant rooves as polygons using aerial imagery from Bing. If I can't find any better quality images, I would still be interested to hear about the method you are suggesting, looking at different times of the day.

@elrobis the neighbourhood area is about 500m by 1.25km. I don't have a DEM yet, but I need to do one at some point.
