We love building useful tools from open data. Our other hobby project, POI Explorer, is a geographic directory of points of interest from around the world. It lets you explore everything from continents down to individual street-level venues, all powered by open-source data from OpenStreetMap, GeoNames, and Who's On First.
Whether you are planning a trip to a Disney park or just exploring a new city, POI Explorer makes it easy to discover what is around you. Both projects share the same philosophy: take great data, build something useful on top of it, and give it away for free.
