Plenario is a centralized hub for open datasets from around the world, ready to search and download.
All data in Plenario exists on a single map and a single timeline, making it incredibly easy to access multiple datasets at once—especially those originally housed at different data portals.
Anyone can add datasets to Plenario via the Add dataset form. You can add any publicly available URL for a CSV or Socrata dataset that includes a unique ID, date, and location information.
No coding, no NDAs, no navigating government websites older than you are. Accessing the data is as easy as selecting dates and drawing on a map. (Don't worry, you can still code.)
City data portals, the federal government, individual datasets—we have it all, whether originally housed at Socrata or CKAN data portals or in CSV format.
With all the data at your fingertips, you can watch places change over time.
Here’s an example: Get a week-by-week look at downtown Chicago since 2013.
Plenario is fully open source, collaborative, extensible, and growing every day. It isn’t just a platform—it’s a community and a new way to think about open data.
