Today, the City announced the release of dozens of high-value data sets, an enhanced NYC Open Data portal at, and the citywide plan for unlocking all public data by 2018.

These developments mark the latest milestone in NYC Department of Information Technology and Telecommunications’s (DoITT) implementation of Local Law 11 of 2012, the landmark open data legislation signed by Mayor Bloomberg last year. The NYC Open Data Plan ensures New York City continues to release public data for generations to come, providing a detailed schedule of the data sets that City agencies will release to the public in compliance with the law.

Also, included in this release are new open data covering a wide range of topics, from property and construction to health and environmental data. 

Explore more than 200 new data sets available free of charge on the newly redesigned, bringing the total to over 1,100 data sets from over 60 city agencies open to the public.

Calling all Data Enthusiasts! 

The first NYC Data Week, co-produced by the New York City Department of Information Technology & Telecommunications (DoITT) and O’Reilly Media’s Strata Conference + Hadoop World spans October 22-26, 2012. The week’s line-up includes a Startup Showcase with Fred Wilson and Tim O’Reilly, Ignite NYC @Strata, a hackathon, and several meetups. 

As part of the citywide celebration, data champions are also invited to help plan the week by adding their own events to a crowdsourced calendar. Join the celebration!

This weekend, the New York City Departments of Information Technology & Telecommunications (DoITT) and Parks & Recreation (DPR), along with partner DataKind – a community of data scientists dedicated to solving challenges through data – hosted the first-ever NYC City agency DataDive. The event allowed data enthusiasts to work directly with Parks data on the urban forest to uncover innovative ideas and solutions.

Using a variety of datasets including an NYC tree census (a feed with more than 600,000 of the City’s street trees available on the NYC OpenData portal) Parks asked DataDivers to help with the following challenges:

  •  How has the City’s tree species composition changed over time, and what it will be in the future?
  • How we can predict where our urban forest will be most vulnerable to storms?
  •  Does programmatic maintenance reduce future citizen requests in an area? E.g. tree pruning

Using tools like CartoDB to dynamically map tree data, teams came up with impressive results under tight time constraints. Check out this awesome NYC tree diversity explorer, an early map showing storm damage risk areas, and one team’s process used to investigate the impact of tree pruning.

During the weekend, the teams also took breaks to hear talks and demonstrations by the NYC Mayor’s Office of Policy & Strategic Planning, NYC Center for Innovation through Data Intelligence (CIDI), and Palantir.

Huge thanks to all who participated! Stay tuned for an announcement about the next DataDive in late October 2012.

Two weeks back, over a dozen NYC gov folks joined Open NY, a group devoted to technology and open government, to explore how we can support open data initiatives. Thanks to organizer Noel Hidalgo and the participants, the evening was a fruitful, constructive discussion of our City’s digital future.
