## FAQ

### What URLs are oneboxed?

`http://www.openstreetmap.org/?mlat=[Marker Latitude]&mlon=[Marker Longitude]#map=[Zoom Level]/[Latitude]/[Longitude]&layers=[Layer code]`

### Why URLs without *Marker* parameters are not being oneboxed?

The `map` parameter is located inside URL hash.
Root URLs without query parameters are currently [ignored by onebox library](https://github.com/discourse/onebox/blob/d94d4ef7dffaf299b2b1cd673e9f7d4f3b5da9dc/lib/onebox/matcher.rb#L17).
This is a temporary inconvenience: [upstream fix is awaiting approval](https://github.com/discourse/onebox/pull/252).

### I don't like oneboxing: can't I just copy&paste `<iframe>` code from OpenStreetMap.org's share menu?

Sure you can: this plugin whitelists posting iframes from openstreetmap.org.
