Back in 2013 maps were generated almost daily to track the immediate usage of the then new coordinate location within the project. An animation was then created by Denny & Lydia showing the amazing growth which can be seen on commons here. Recently we found the original images used to make this animation starting in June 2013 and extending to September 2013, and to celebrate the fourth birthday of Wikidata we decided to make a few new animations.

Wikidata Map October 2016
I has been another 5 months since my last post about the Wikidata maps, and again some areas of the world have lit up. Since my last post at least 9 noticeable areas have appeared with many new items containing coordinate locations. These include Afghanistan, Angola, Bosnia & Herzegovina, Burundi, Lebanon, Lithuania, Macedonia, South Sudan and Syria.
The difference map below was generated using Resemble.js. The pink areas show areas of difference between the two maps from April and October 2016.
Geospatial search for Wikidata Query Service
Geospatial search is up and running for the Wikidata Query Service! This allows you to search for items with coordinates that are located within a certain radius or within a bounding box.
Along side the the map that can be used to display results for the query service this really is a great tool for quickly visualizing coverage.
Wikidata Map May 2016 (Belarus & Uganda)
I originally posted about the Wikidata maps back in early 2015 and have followed up with a few posts since looking at interesting developments. This is another one of those posts covering the changes since the last post, so late 2015, to now, May 2016.
The new maps look very similar to the naked eye and the new ‘big’ map can be seen below.
So while at the 2016 Wikimedia Hackathon in Jerusalem I teamed up with @valhallasw to generate some diffs of these maps, in a slightly more programatic way to my posts following up the 2015 Wikimania!
Myanmar coordinates on Wikidata by Lockal & Widar
In a recent blog post I showed the amazing apparent effect that Wikimania’s location had on the coordinate location data in Mexico on Wikidata. A comment on the post by Finn Årup Nielsen pointed out a massive increase in data in the Myanmar (Burma). I had previously spotted this increase but chosen not to mention it in the post. But now after a quick look at some items and edit histories I have found who we have to thank!
The increase in geo coordinate information around the region can clearly be seen in the image above. As with the Mexico comparison this shows the difference between June and October 2015.
Impact of Wikimania Mexico 2015 on Wikidata
Recently Wikidata celebrated its third birthday. For the occasion I ran the map generation script that I have talked about before again to see what had changed in the geo coordinate landscape of Wikidata! I found, well, Mexico blossomed! The image to the left is from June 2015, the right October 2015 and Wikimania was … Read more
Wikidata Map – 19 months on
The last Wikidata map generation, as last discussed here and as originally created by Denny Vrandečić was on the 7th of November 2013. Recently I have started rewriting the code that generates the maps, stored on github, and boom, a new map! The old code The old version of the wikidata-analysis repo, which generated the maps (along with other … Read more
Wikidata map visualizations
In 2013 and 2014 I made a few presentations to various groups of people talking about Wikidata.
When creating those presentations I used as many graphical representations of the data in Wikidata as possible to try and give people an clearer picture of what is already stored.
One of the best visualisations at the time was the Wikidata map created by Denny Vrandečić which came after the introduction of coordinate locations to Wikidata.
Below you can see a GIF showing the additions of the coordinate location property to Wikidata items over roughly the first 40 days of enabling the coordinates data type.
