As longtime stewards of New York City’s trees, we understand that community participation is essential in maintaining urban forests. That’s why we are providing tools to developers to help build on our Tree Map platform and data for use in New York City and around the world.

Open Data

The foundation of the NYC Street Tree Map is the tree data managed in Parks' forestry management system. While the Tree Map gets daily updates from this management system, developers can find the most recent snapshot of the tree data set on the NYC Open Data Portal.

NYC Parks has also shared supporting data sets from the Tree Map on the NYC Open Data Portal, including data feeds for: favorited trees, eco-benefits of trees, anonymized tree-care-stewardship activity, tree edit suggestions, and stewardship groups.

In addition, we have shared all of the tree data that was collected in the 2015-2016 tree census on the NYC Open Data Portal, which served as the initial basis for the tree data within the tree map.

In the future, once additional features and reporting can be prioritized and deployed, we will subsequently prepare the codebase to be shared as an open source repository on GitHub, allowing other cities to reuse and extend the code base, and allow individual developers to highlight issues and suggest improvements and new features.

Open Source Credits
