The Spelunker

The Spelunker is a internal tool we built for poking around and investigating Who's On First data. It was so useful we made it public! The Spelunker lives at:

https://spelunker.whosonfirst.org/

To find out more about the Who's On First API we recommend reading the 2015 blog post introducing the Spelunker and Dan Phiffer's "WOF in a Box" series (parts one and two) about setting up and running the Spelunker locally.

"Places"

For any given Who's On First ID there is a permanent human-friendly rendering available from:

https://places.whosonfirst.org/

There is no search interface for these renderings or even a table of contents style index so you need to know which Who's On First ID you're looking for. The URL for a given place looks like this: https://places.whosonfirst.org/id/{WHOSONFIRST_ID}.

For example here's the "places" URL for Montreal:

https://places.whosonfirst.org/id/101736545/

If you're wondering these pages exist as a fail-safe for when services like the Spelunker or the API are offline or otherwise unavailable. It's not a perfect solution but it's better than forcing people to look at raw GeoJSON files.
