Points with the same lat/long do not cluster

[demoend]

I think you are on the right track with your AD cluster map view, I appreciate your effort and desire to share you code with others. But it only works well to a point for me.

Using the sample project, if I change some of the point data in the CDToilets.json file to have the same lat/long then those points will not cluster. This was at maximum zoom. Looks like they are just on top of each other and I cannot pick the point underneath the top one.

Example: If I stand in one spot for a while and snap 10 photos, I most likely will have photos with the same lat/long. Some photos may be so close that they should always bee seen as one point. The user then will need to click on the blue arrow in the callout to drill down to the exact photo they are interested in. The Apple photo app does this same type of thing.

This is an interesting use case, but I'm not sure it has anything to do with clustering actually.

The aim of clustering is to remove reduce the number of visible annotation for a nicer and faster UI.

Here it's actually your annotations themselves that aren't properly built. Your model objects aren't correct: instead of adding one annotation per photo, you should add one annotation per "photo list", where a photo list is defined as a group of photos sharing the same coordinates (or nearly the same coordinates).

That being said, your use case is pretty common I guess, so it might make sense to work something out.
