Helsinki Region Infoshare (hri.fi) publishes 548 open datasets for Finland. Browse them live in Vizzie and turn any one into a map or chart.
Helsinki Region Infoshare (hri.fi) is the open-data portal for Finland, covering Uusimaa. It runs on CKAN, an open catalogue standard used by many national governments. You can browse it directly at hri.fi/data.
On Helsinki Region Infoshare (hri.fi), most datasets here are clearly licensed — only a small share are undeclared. 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 548 datasets here whose licence Vizzie can identify, essentially all of them can be used commercially; 0% carry a share-alike condition, so work built on them has to be published under the same terms. Attribution is required by almost every open licence — Vizzie writes the attribution line for you when you export or publish.
Helsinki Region Infoshare (hri.fi) doesn't expose a machine-readable breakdown of who publishes what, so there's no reliable publisher ranking to show here. Vizzie still surfaces each dataset's own publisher as you browse.
