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.

APIs and Open Data

Currently we have shared all of the tree data that was collected in the 2015-2016 tree count, which served as the basis for the tree data within the tree map, on the NYC Open Data Portal for citizen and developer use.

In the future, once additional admin features and reporting can be prioritized, developed, and implemented, we will then look to provide open APIs for developers to request tree, and anonymized tree care activity, to use in their own projects. And subsequently the codebase will be shared as an open source repository on GitHub, allowing other cities to reuse and extend the code base, and individual developers to highlight issues and suggest improvements and new features.
