Quality looks similar to the digitization of pdf plans in France. The
raw outline may be vaguely useful, but a lot of fine detail simply gets
lost? The digitized versions may be useful as sources for details to be
manually copied, but fully automatic importation is to be avoided!
As with the French data, and a lot of third party data, the main problem
when working with an historic view is combining objects which are the
same between different maps. Has a building shape changed because it's a
new building, or has had an extension for example.
What is the French data you are referring to?
I was quite impressed with the crowd-sourcing aspect of the NYPLs
Building Inspector; somewhere I saw it described as a 'bus stop' app,
meaning it is easy to dip into, and make use of those moments spent
waiting for buses or suchlike. And also, these corrections don't only
correct the data overlaid on the map, but are fed back into making the
program better at picking out correct polygons.
Wired article giving more background:

The NY Chronology of Place looks interesting as well, tho' I can't find
much in the way of background info about it:
