Getting Started With Open Data
NYC Open Data allows New Yorkers to engage with the information that is produced and used by the City government.
The following tutorials will show you how to filter, map, and export 311 Service Requests during a particular time period. 311 is New York City’s non-emergency call center that allows residents to make service requests, file complaints, and get additional information about the City.

Some quick tips for navigating
NYC Open Data
- Data Dictionaries should be your key resource
Data can be complex. Some datasets contain millions of records and many unfamiliar terms. Be sure to review a dataset’s primer page for additional information about a dataset, including its data dictionary. In the data dictionary, you’ll find definitions of terms and values in the dataset.
- Filtering is critical for navigating large datasets
In general, if you experience difficulty manipulating and downloading larger datasets, you should restrict the number of records that appear using the “filter” function. In this panel, users may “Add a New Filter Condition” and select attribute values that are exact matches with the “is” condition, or fall within a range of values with the “contains” condition. A narrower selection of results will require less computing power to view and manipulate data, and will create smaller data files that are quicker to download onto your local device.

- Want to win that hackathon or build the next great Open Data app? Get started with Socrata APIs.
- Socrata APIs provide rich query functionality through the “Socrata Query Language” (SoQL), which borrows heavily from Structured Query Language (SQL). Its paradigms should be familiar to developers who have worked with SQL and easy to learn for those who are new to it.
- The “endpoint” of a SODA API is a unique URL that represents an object or collection of objects. Every dataset, and even every individual data record, has its own endpoint. The endpoint is what you’ll point your HTTP client at to interact with data resources.
