What's this laser scanning? Vector topographic data and aerial imagery is all that's necessary.

Theoretically just the aerial images would be enough if you have some control points. But I remember the Nokia people say they used mobile laserscan data. Can't find the source anymore though, I thought it was on HN actually.
