I hadn't seen Panoramax before, but I'm finding exploring it frustrating.

If I look at Melbourne I see there is some data: https://api.panoramax.xyz/?focus=map&map=5.99/-37.126/147.65...

But if I zoom in the data points disappear: https://api.panoramax.xyz/?focus=map&map=7.45/-37.333/146.16...

Eventually, by random scanning: https://api.panoramax.xyz/?focus=map&map=18.07/-38.084429/14...

I found one point: https://api.panoramax.xyz/?focus=map&map=18.89/-38.0848624/1...

How am I supposed to discover the coverage?

We may have some bug in the clustering showing too much dots at low zoom levels.

Panoramax coverage is mainly located in France as the project started there. It is a decentralized and federated effort and there is not yet a Panoramax server covering Australia. OpenStreetMap France Panoramax server accepts pictures outside of France, but for testing only.

A test sequence is available here: https://api.panoramax.xyz/?focus=pic&map=18.24/-38.123153/14...
