This type classification is not used anywhere, not even as a filter for results 
from the API, from what I heard.

this is not a blocker to Special:Nearby but is still something we should do 
soon, in order to make GeoData on Wikidata more useful.

[Wikidata-bugs] [Maniphest] [Commented On] T115481: [Task] Set type parameter for GeoData coordinates in Wikibase

thought about this yet some more

What we could do is have a "mapping" of the geodata types to 
https://phabricator.wikimedia.org/P31 (instanceof) values and subclass values.  
This would prevent a proliferation of thousands or who knows how many 
instanceof types for geodata, yet use already existing information from items.

For example, Q55488 = 'railway station' and that has 90 subclass items. (e.g. 
"S-Bahn station", Q1793804).  We could have a maintenance script (using the 
query service) that generates and updates these mappings between geodata types 
and instanceof values.

The type to https://phabricator.wikimedia.org/P31 mapping would be 
configuration, so we don't hardcode this knowledge in wikibase. The mappings 
could be stored in a database table and cached somewhere (memcached?) or 
depending on how large the mapping is, maybe file-based caching, APC, or 
something?

If, at some point, we wanted to add more geodata types, then I think it would 
be easy enough with this approach to do so.

For dim, we can default to the type-to-dim mapping, but perhaps if an item has 
the area property set, length (e.g. for a river), or 
northern/southern/eastern/westernmost points, then we could use those for dim.

Besides Daniel's question: I would very much prefer to not have this stored as 
statements on millions of items.

What are the intended use cases for the type, besides estimating dimenstion? 
What is currently using type?
