The UFO API is a collection of UFO Sigthings served through an API.
The original dataset is coming from The National UFO Reporting Center. The data has been modified and augmented with location data, to allow for easier querying and location based queries.
An example of a visualization using this data can be found here.
The API is currently hosted https://ufo-api.herokuapp.com/api
This project is created by Joakim Gregersen Quach for the class Designing for Data Personalization taught by Sam Slover at ITP, NYU.
