Hoi, Stas this sounds absolutely wonderful. Magnus has in his software a lot of use of similar functionality. It is wonderful to see that it is now coming to Wikidata itself. Magnus is moving away from his WDQ and I think that is wonderful on many levels. (It makes me feel like a dinosaur because I still have to learn the rudimentary skills to do what I always do)..

With practical examples like the ones Magnus offers, people really get the idea why this is such a wonderful thing. Only think of every Wikipedia article without a picture :) Or all the items that are part of a specific project..

It will be interesting to see what people come up with. Thanks, GerardM

Hi all!

I would like to present to you a preview of an upcoming Wikidata Query Service feature, namely geospatial search - on http://geotest.wmflabs.org/. With this, you will be able to search things by their geographic coordinates, e.g.:

Objects within 10km of Paris: http://tinyurl.com/jaxr3bn

Airports within 100km from Berlin: http://tinyurl.com/gtbmqz3

(try also the map view!)

The purpose of the preview is to let people play with it and collect feedback on what works, what doesn't and what you'd like to see added/changed/removed.

This is a preview implementation, so do not use it for anything beyond admiring the marvels of modern technology :) and providing feedback. The full release on query.wikidata.org will follow sometime in late April-early May, hopefully.

What is implemented?

• Coordinate storage & indexing as WKT literals
• Search within radius and within bounding box
• Support for different globes

What is missing but would be added soon?

• Distances as search output and as separate function
• Documentation
• You tell me

Thanks,

Stas Malyshev smalyshev@wikimedia.org

Hi!

Great to see this!

But is it down? I get "Data last updated: [connecting]", and queries run forever...

Thanks, should be fine now.
