Hello, so I have 3.5 Mio objects in my database that are coming from 42 Wikipedias. There are also some objects from projects like WikiLovesMonuments. Wikidata contains only 1.2 Mio articles, but I hope this is only a question of time to have all objects.
The database is available on WMLabs now[1].
Each object on the map have pop-up and on the end of it there there you can find the source. I have in the moment a problem with nl.wp because they doesn't work in my source from User:dispenser[2].
The problem with kangaroo-isle was a missing icon, it works now.
Greetings Tim

Kolossos, Thanks for this work - it's fascinating to see the huge gaps in the data and I was wondering if maybe this reflects the work of lots of individuals who have input those properties by hand, or whether some people have enabled clever bots for their regions that other regions could reuse? (hopefully)
I can see at a glance in the case of the Netherlands that not all objects in the subclass lists that are in the English (or Dutch!) Wikipedia with geo-coordinates are in the overlay maps, so I was wondering how the data got in there. I was also interested to see some slight incorrections in the coordinates for certain subclasses (probably based on some older geocoordinate conversion software for some specific database).

Hello, I'm glad to can announce my last experiment working with Wikidata and Wikipedia-coordinates: http://tools.wmflabs.org/wp-world/wikidata/superclasses.php?lang=en
This list shows how many objects we have in different classes and provide links to maps with only this specific class.
I think it's much more useful than in the past where 80% of our coordinates were simply a "landmark". Now we have maps full with roller coaster or with museums.
To create this tool I used properties "is instance of"[1] and "is subclass of"[2]. To extract this properties it was necessary to use "Wikidata Query".
Now all classes, where an object is a member, are in a numerical array-element in the database. So with an index on this array it should have a good performances.
Next steps are to try to bring more order inside this list and support the community to create more "is instance of"-entries in Wikidata. (Only 30% off all objects have such an entry).
Greetings from Switzerland Kolossos
