We do need to be very careful here. Suffolk County, at least, considers 
its tax rolls as subject to copyright - and the Court of Appeals for the 
Second Circuit agrees. (The case reached the courts because a realtors' 
Multiple Listing Service imported the tax parcels, and the county sued 
for copyright infringement.) The Second Circuit stands alone in making 
that determination, which flies in the face of principles of open 
government, but until and unless the decision is revisited, it's good 
law. It won't be overturned based on the original case, which is now moot.

Importing from http://nypad.org/Download/GDBv1.1 would be attractive, 
but the license terms are unacceptable. We can't promise to update at 
least once a year in perpetuity, or assume liability if OSM users 
trespass, or restrict the display of data to the resolution specified in 
the metadata.

It used to be that NYSGIS had a shapefile for public non-DEC recreation 
lands in New York, but they withdrew it at the demand of
the contractor who produced it.

http://gis.ny.gov/gisdata/metadata/nysgis.NYS-Tax-Parcels-State-Owned.pdf is 
a possibility, but coverage is very incomplete. Only seven counties, 
plus New York City, participate in the program.

http://gis.ny.gov/gisdata/inventories/details.cfm?DSID=430 is not 
released publicly. I have a copy that a contact of mine demanded under 
the Freedom of Information Law (FOIL). I'm not going to presume that it 
can be licensed for OSM.

In general, the government functionaries in New York are terrified of 
losing control of the data. The thinking tends to be, "what if someone 
gets in trouble based on obsolete or inaccurate or inappropriately-used 
data and I'm held responsible because I allowed them to use it?" A 
far-fetched scenario, but it's the way low-level government officials think.
