Geoservice API

The Geoservice API is a RESTful web service interface to the NYC Department of City Planning’s core Geosupport system. Geosupport is a geocoding system used by NYC government. Geosupport provides coordinate and geographic attributes for supported input locations (address, intersection, blockface, BIN, BBL). Geoservice exposes all the Geosupport functions through simple and easy to use REST representations.

How to use Geoservice API

Each URL accepts some parameters; for example, Borough={Borough} where Borough is the name of the parameter and {Borough} is the value assigned to Borough. Acceptable borough values


For the complete accepted parameters, refer to each function page, and to assign proper values to each parameter, refer to the User Programming Guide (UPG).

Display Format DisplayFormat

Each URL has an optional DisplayFormat parameter. By default, this parameter is set to true, which returns a beautified version of GeoX. To return the raw data i.e. Work Area 1 and Work Area 2, set this parameter to false.
