There are currently gaps in the park data (e.g. Tallman, High Tor,<br>
Hook, and Storm King parks are all missing) and boundaries for at<br>
least Harriman /Bear Mountain state parks don't match official<br>
records. I am hoping that I can build consensus on importing state<br>
and federal lands from New York state county level tax parcels. I've looked at a few counties so far at it appears that there<br>
aren't restrictions on how the data can be used, though obviously<br>
each county needs to be evaluated and permission sought if nessecary.<br>

Adding missing parks and updating boundaries of existing parks would be welcomed. If you haven't reviewed the import guidelines [1], that should be step 1. Making sure the data is appropriately licensed for import into OSM should be your next step. This list can help you make that determination. When you create the import wiki page, make sure to include link to the license. Finally, I would recommend posting this on talk-us to get buy in from the US community.<br>

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.<br>

Importing from <a href="http://nypad.org/Download/GDBv1.1" rel="noreferrer" target="_blank">http://nypad.org/Download/GDBv1.1</a> 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.<br>

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<br>
the contractor who produced it.<br>

Only seven counties, plus New York City, participate in the program.<br>

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.<br>

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.<span><font color="#888888"><br>
