However normally it's neccessary to go out on foot(or car or bike...) to collect street names or POI's so (I think) most people tend to work in this mode.
I usually go out and come back with photo's and GPS traces and then enter these, the aerial photography is still really useful for additional things like tracing out area's or filling in gaps where GPS coverage wasn't good.
