Most of the houses here are my work:

Thus I think the Walking Papers is far more useful than we rwalise. I used to work for a German company Photogrammtrie GmbH - Europe's oldest mapping firm - and one important aspect of mapping is as we call it - ground truthing. Vital that we collect this info.

That's cool. Do you have any sort of order to what you capture?

A cursory glance shows that there seem to be many buildings missing in my town. All the streets seem to be in OSM though.

Out of interest, how are you photographing your town? Is the camera mounted underneath the plane as in conventional aerial photography?
