AODN publishes 398 open datasets for Australia. Browse them live in Vizzie and turn any one into a map or chart.
AODN is the open-data portal for Australia. It runs on OGC Web Feature Service (GeoServer), an open-data platform. You can browse it directly at geoserver-123.aodn.org.au/geoserver/wfs.
On AODN, 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.
Added 20 Sep 2026. Australia's marine and climate observing data — IMOS moorings, CTD profiles, animal tracking, vessel tracks — as 398 live vector layers. Reached through the WFS rather than AODN's CSW deliberately…
AODN 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.
