The Geoclient API is a RESTful web service interface to the NYC Department of City Planning’s Geosupport system developed by the Department of Information Technology and Telecommunications GIS/Mapping unit. Geosupport is a mainframe-based geocoding system used by NYC government. Geosupport provides coordinate and geographic attributes for supported input locations (address, intersection, blockface). Geoclient exposes the most widely used Geosupport functions through simple and easy to use REST representations.
The Geoclient API is a free geocoding service offered by the City of New York for use by the general public. Access to the service requires registering for a free account on this website and requesting an access key.
Due to rapidly increasing usage of Geoclient, we are seeing a commensurate decline in overall application availability based our current contractual resource allowance from third party platform services. While we work towards increasing this capacity, we are forced to set service usage guidelines.
From this point forward, the following service usage guidelines apply:
·Maximum of 2,500 requests per minute;
·Maximum of 500,000 requests per day.
Note that these are guidelines and not hard limits. However, if we see applications continually exceeding these limits, we will attempt to notify the account administrator based on contact information provided in the sign-up forms. If corrective action is not taken, we will then set whatever limits we deem necessary to provide equal resources averaged by all active accounts. Moving forward, as we increase capacity, we may adjust the usage guidelines.
New York City agencies requesting use of this service for any purpose should contact the DoITT GIS team directly for appropriate access.
The source code for the Geoclient API project was released under the Apache 2.0 license and is available for download on GitHub. Since the Geoclient API relies on Geosupport for the actual geocoding, the Geosupport binaries need to be downloaded from the NYC Department of City Planning website. By downloading and installing Geosupport, you can run Geoclient on your own servers.
