In the US, literally billions of dollars have been spent collecting
geospatial data over the past 20+ years at all levels of government. A
very sizable portion of that data is free of restrictive licensing (and
getting better at the state and local level every year). That's a lot of
work done - millions of man hours? I think a lot of people in the US
look at existing available data and say to themselves, why duplicate all
that effort? It doesn't make any sense.
I think its more helpful to discuss what types of features lend
themselves to imports vs. not. There seems to be a strong consensus in
the US that addresses and buildings are strong candidates for import.
Why spend hundreds of thousands of man hours to recreate something that
has already been done by local governments throughout the US? Of course,
data quality and licensing has to be vetted, but it just simply does not
make sense to replicate all that work. Especially since we have proven
methods for importing that data without damaging existing data.
