BUILT HERE · CITY MAP

New York's transit and its precincts on one map

One interactive map of how New York moves and who keeps it safe: every subway line and station drawn over the city's 77 police precincts, with each precinct's address and desk phone, and the regional rail lines that feed the city.

What it is

Tap a precinct for its address, desk phone and community affairs contacts. The commuter railroads, Amtrak, NJ Transit, PATH and intercity buses are on the same map, with links out to their live service pages.

It is one fast page that works on a phone in the street.

Who it is for

New Yorkers and visitors who want to know which precinct they are in and how to reach it, and anyone planning a trip across the region.

How it started, and how I built it

The map stitches together public data that normally lives in separate places.

  1. Official data. Precinct boundaries come from New York City's planning department; contacts come from each precinct's own NYPD page.
  2. One light page. A single page on an open-source mapping library, with the map data served alongside it. No app to install.

What it shows I can do

  • Combining public data sets into one clear, useful view.
  • Building maps that work on a phone, fast, without heavy frameworks.

For a client, the same skill maps assets, sites or service areas so people can see them at a glance.

Questions people ask

Where does the data come from?

New York City's planning department and NYPD precinct pages, plus the transit agencies' own maps.

Does it show live train times?

It links to each agency's live service pages rather than copying them.
