#30DayMapChallenge Day
: Conflict
I figured a lot of mappers will create maps about recent wars and conflicts so I decided to create a map about #WorldWarI and see if #Wikidata is a good enough source for its battles, conflicts, and military operations.
I also wanted to know if there are any open data sources for historical borders, and I found one, CShapes! https://icr.ethz.ch/data/cshapes/

I’m not sure if #Wikidata is complete or accurate but looking at the map, and not being a WW1 expert, I’m actually surprised that there’s very little activity inside #Germany. The Western Front is quite obvious, and southern #Finland is quite active. The Middle East is also seeing a lot of action.
I again used my Day 13 new tool #D3js to render an Albers equal-area map of #Europe with standard parallels at 35°N and 65°N.

To head off a class of potential questions about the data, here’s the Wikidata Query Service (WDQS) SPARQL query I used: https://w.wiki/C9RM
Just run it and browse and inspect the interactive map of results!
@seav what's the point right in the middle of France? A bit far from the front, this one
@julbriman According to Wikidata, it's the Battle of the Frontiers: https://www.wikidata.org/wiki/Q687572
I’m quite sure the coordinates in Wikidata are wrong because they’re too imprecise and are far from the front lines.
@seav oh, I see. That's not really a battle like Verdun or Gallipoli, more like a series of fights all along the Western front. Not sure one can actually pinpoint coordinates for such an event (imagine having coordinates on the item "World War I"…)
@julbriman oh I see. In that case, I just deleted the coordinates for this in Wikidata. (The coordinates are unreferenced anyway, so deleting it is fair game.)
@seav I see this in coverage in general. Maybe it's related to where the most fortifications were?
@seav Thank you so much for pointing me to the CShapes package! I’ve been looking for shape files of the late Ottoman Empire for years.
@lavaeolus @seav Thanks. I remember cshapes had pre & post WWII maps but didn’t have any representing lines of control during war (e.g. after sept 1939) which was what I was going for. Still have a desire to create those if I can’t find em.
