What we believe

Public data belongs to everyone. So should the power to use it.

ACCESS
Make public data usable by anyone, closing the tools-and-expertise divide.
CAPACITY
Help non-specialists and mission-driven organisations put data to work.
ADVOCACY
Champion open data, interoperability, and open standards, supporting the movement behind them.

Aligned with the Open Data Charter.

How it works

From open data to a finished map, in one place.

Connect

Browse and connect to thousands of open-data portals around the world in real time. Nothing to download or reformat.

Explore

Map, chart, and analyse place-based data together on one linked canvas. You get powerful spatial analysis without having to be an expert.

Share

Turn what you find into presentation-ready maps and interactive stories you can publish and share with a link.

See it in action

From a portal to a map, in a minute.

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.

Searching Vancouver, choosing the City of Vancouver open-data portal, finding the street-trees dataset, previewing it, then adding it so it maps and charts itself

150,000 street trees, in 3D.

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.
