Where would I be able to obtain or purchase GeoJSON data for Manhattan submarkets?

Question

GeoJSON data contains arrays of coordinates that create polylines (like borders). You can find geoJSON data for the 50 U.S. state borders, for example. I would like proper geoJSON data for this: https://www.scribblemaps.com/create/#/id=HfPjzTz28R&lat=40.76084989&lng=-73.98615251&z=14&t=mbb_road

Does anyone know where I would find or commission this? It's going into a Kotlin-based web endpoint that creates maps.

Answer 1

Try the open data portal for NYC. For example, the NYC borough boundaries GIS data.

Answer 2

If by “submarket” you just mean “neighborhood” then there are plenty of open sources

For example: https://github.com/veltman/snd3/blob/master/data/nyc-neighborhoods.geo.json
