Well at least the Tiger data included further information outside of
just geometry and I'm saying that as a well known Tiger import hater.
Supposedly the cadastre includes street names and house numbers, however
of the 27 million buildings (plus 6 million wall=no) only a minuscule
number have further information attached, matter of fact there are more
nodes with addresses tagged in France than there are building outlines
with house numbers. Why this is the case, I don't know, but house
numbers etc. would be of far more immediate benefit to our data than
just building outlines.
