Make your own map of NYC

So you want to make a map of NYC. You are familiar with the NYC Open Data Portal but have had some difficulty in finding all the data you need. You have the requisite software to construct the map (e.g., QGIS, ArcGIS, MapBox Studio, etc.) and the basic skills to do so. Perfect, read on.

This post is intended to provide a single source for the map ingredients. It is not intended to be the map cookbook. It’s up to the reader (i.e., mapper) to decide on data to include, colors, symbols, labels, fonts, etc.

NYC Planimetrics

The table below lists NYC DoITT geospatial data on the Open Data Portal and provides a very basic description of each data set. For more detailed information, see the included metadata. The table is grouped into core basemap features and other DoITT data.

The first grouping of data comprises the data used to construct the above map. These data are referred to as the planimetrics (aka NYCMap). Planimetrics are features captured from aerial photography and represent the City’s basemap. These features are updated on a four year cycle. Most but not all features are provided to the public. Utility structures is one that is not due to security concerns. For an historical perspective and to see how far we have come, read the following article on NYCMap. *Note the full article requires a subscription.

The second group represents other NYC DoITT data that may be of interest but is not necessary for producing a basemap. Some of these data are maintained directly by DoITT and others are compiled from agency sources. We do our best to keep these data current.

The last group includes notable geospatial data sets not managed by DoITT and agency sites where spatial data can be found.

Every effort will be made to ensure the above table is complete and the links are current. If you find an error or omission, please feel free to add a comment below to let us know. Lastly, check back periodically as this table will be expanded as newer data sets are published.

Happy mapping!

  1. Hello Colin,

    Sorry for entering this question here, I don’t know how else to contact you.

    I am trying to create a roadbed dataset similar to the NYC one, for Jersey City. It would be a first for me and I don’t know exactly how to go about it. Could you help with some information and/or advice?

    Thank you.

    • The NYC roadbeds were digitized photogrammetrically using stereo imagery. This requires specialized software and imagery with a percentage overlap. It’s called planimetric mapping. You can search around but there is no way I can explain the entire process. I guess alternatively you could just go with heads-up digitizing and digitize the roadbeds onscreen over aerials. You’ll need aerials and GIS software. Good luck!

      • Thanks, I guess I’ll roll my sleeves and start digitizing.
        I have another question regarding buildings datasets. There are Building Footprints and PLUTO. Building Footprints has roof height info and PLUTO number of floors, but the data is not per building but by lot. Is there a way that I can somehow use/combine the two datasets so that I can get the floor numbers into the Building Footprints?

        Thanks again.

      • You could do a spatial join. The problem is that there can be multiple buildings on a lot. I would not assume all buildings on a lot are the same number of floors.

    • You should request it from Jeffrey Wenger at the Jersey City Division of Planning. I received the Jersey City roadbed line file from him a few years ago for a planning contract for Jersey City Public Schools. If the City is reluctant to share it with you, make a FOIL request.

    • Thanks for the heads up.

      Landmark data was consolidated and the historic districts were not properly updated; therefore the link broke. Everything should be good now.
