New York City liberates map data trove

The Newyorkworld: New York City streets are free to walk, but until now getting the city’s master map database cost dearly.
That changed on Thursday, when the Department of City Planning made MapPLUTO — an extensive database full of information about each of the city’s parcels of land — available to the public on its website, free of charge.

Previously, the same files came at a steep price of $300 per borough, and a required license barred users from posting any of the data, including maps, on the Internet.
“We revised our policy on the sale of PLUTO and MapPLUTO data in keeping with the Mayor’s ongoing commitment to using technology to improve customer service and transparency,” a Department of Planning spokesperson wrote in an email on Thursday.
In April, The New York World reported that even as the city moved to put vital government data online for free download, MapPLUTO remained a glaring exception.”
