🗺️ Day 2️⃣1️⃣: Conflict

I figured a lot of mappers will create maps about recent wars and conflicts so I decided to create a map about and see if 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! icr.ethz.ch/data/cshapes/

🧵 1/2

I’m not sure if 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 . The Western Front is quite obvious, and southern is quite active. The Middle East is also seeing a lot of action.

I again used my Day 13 new tool to render an Albers equal-area map of 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: 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: 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.

www.wikidata.orgBattle of the Frontiers1914 series of battles; part of the Western Front of World War I

@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?

@egonw @seav it should be coordinates of battles or campaigns.

@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.

@seav Just spun up #rstats while waiting for the kid at the public pool and was finally able to quickly plot the distribution of Arabic periodicals on a political map for 1900. #CShapes is amazing!!!!

@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.
