Hi Max and Oliver,

Thanks for your answers. geo_tags table seems quite uncomplete. I just checked some random articles in for instance Nepali Wikipedia, for its Capital Katmandú there is coords in the real article but it doesn't appear in geo_tags. Then it doesn't seem an option.

Max's idea is an improvement but still a lot of requests. We really need to start generating these dumps :(.

Until the dumps are available, the fastest way to do it is probably Quarry (http://quarry.wmflabs.org/) an open MySQL client to our public database tables. So, you want the geo_tags table; getting all the coordinate sets on the English-language Wikipedia would be something like:

SELECT * FROM enwiki_p.geo_tags;

This should be available for all of our production wikis (SHOW DATABASES is your friend): you want [project]_p rather than [project]. Hope that helps!

Hi guys,

I am doing some research and I struggling a bit to obtain geolocalized articles in several languages. They told me that the best tool to obtain the geolocalization for each article would be GeoData API. But I see there I need to introduce each article name and I don't know if it is the best way.

I am thinking for instance that for big wikipedies like French or German I might need to make a million queries to get only those with coords... Also, I would like to obtain the region according to ISO 3166-2 which seems to be there.

My objective is to obtain different lists of articles related to countries and regions.

I don't know if using WikiData with python would be a better option. But I see that there there isn't the region. Maybe I could combine WikiData and some other tool to give me the region. 

Anyone could help me?

Thanks a lot.
