OSM Coverage

Loading map...

The NYC map has looked great for a long time, but the community has been busy fixing things like one way streets (important for navigation applications) and now drilling down in the detail, adding points of interest: cafes, restaurants, etc. And you're welcome to help!

Buildings data

NYC Buildings Addresses import is pretty much complete. This dataset from the city, included building perimeter outlines, heights, and address point data. As of mid-2014 we are in final cleanup mode. Remaining tasks are captured on Github:

3D data of New York City shown in OSG-Maps. This shows the basic extruded buildings with height data from the import, plus you can also see some refined skyscapers colors and roof shapes

Brandon is interested in this.

Other possible imports

Many interested parties are following the progress in NYC's open data movement and the datasets opening up at Some of these are Potential Datasources which could be investigated for import to OpenStreetMap.

Liz, Serge, Alex are some of the people interested in this.
