State of Oklahoma (data.ok.gov) publishes 395 open datasets for United States. Browse them live in Vizzie and turn any one into a map or chart.
State of Oklahoma (data.ok.gov) is the open-data portal for United States, covering Oklahoma. It runs on CKAN, an open catalogue standard used by many national governments. You can browse it directly at data.ok.gov.
On State of Oklahoma (data.ok.gov), a majority of datasets here declare no licence at all. It's important to know that "no licence declared" is not the same as public-domain or free-to-use. Undeclared data carries no explicit permission to copy, adapt, or redistribute it — so reusers should treat it cautiously and check with the publisher before relying on it. Vizzie flags each dataset's licence (or its absence) so you can see this before you build.
Of the 64 datasets here whose licence Vizzie can identify, essentially all of them can be used commercially. Attribution is required by almost every open licence — Vizzie writes the attribution line for you when you export or publish.
The only CKAN in the 2026-09 state batch, so licences arrive as machine ids rather than free text; 64 of 395 datasets declare CC-BY-4.0 and the rest are unset (measured 2026-09-19 over all 395 packages).
