Aligned with the Open Data Charter.
Browse and connect to thousands of open-data portals around the world in real time. Nothing to download or reformat.
Map, chart, and analyse place-based data together on one linked canvas. You get powerful spatial analysis without having to be an expert.
Turn what you find into presentation-ready maps and interactive stories you can publish and share with a link.
Search a place, pick its open-data portal, find a dataset, preview it, and add — then watch it map and chart itself in one click.
Raise each tree by its height and tilt into 3D. Click the legend to filter by species and back, then turn on the zoom filter and zoom in — the charts follow the map to whatever you're looking at.
…and new portals added regularly. Counts as at 6 Aug 2026.
