Hi Majd, I see a big issue with the license of the data, so you'll most likely hit a brick wall as far as importing into OSM goes.
Do you have time for a hangout or a Skype call? I want to show you how easy it would be to create buildings using JOSM. If you can get a group together and do weekly or monthly mapathons, you can draw them from the imagery and the data will simply be odbl licensed.
