But I'm starting to regret mentioning crime in my earlier post. The point I was
trying to make focused on the physical environment, and the fact that a lot of
suburbia in the US is not conducive to walking. In addition, its design and
heavy levels of car traffic make some areas unsafe for walking. I think this
makes suburbia harder to map than older, gridded areas. I've mapped in both. I
live in a suburban setting (because it's close to where I work), but I much
prefer to map in areas that are safer to walk around in.
I've also managed imports of bus stops into several cities where almost none
had been mapped (after trying to contact everyone who had mapped any of them).
So I think technological mediation has value. But there are lots of things that
don't show up on imagery or in public-domain files, and things that don't, such
as stores, bicycle parking, and speed limits, contribute to quality of life. So
my concern was about walkability and suburbia, not about crime.
