Wars of Italy, pt 2
A few more random maps of the Wars of Italy, just because it’s all I’ve got time for.
First off, the locations of various combats (battles and sieges mostly) from 1494-1559, color-coded by war, with the Natural Earth topo layer as base map. It might be more useful to group the wars together into a smaller number of categories (make a calculated field). Or maybe make them small multiples by war. But it’s a start.
Then, using the Data defined override and Size Assistant style in QGIS 2.18, you can add army sizes to the symbols (sizeA+sizeB), to create a multivariate map. Note, however, that I don’t have very many army size statistics (the no-data events are all those tiny dots), but you get the idea – add a continuous variable to a categorical variable, and you’ve got two dimensions.
Remember, with GIS and a good data set, the world’s your oyster.
Next up – getting that good data set. In other words, setting up the Early Modern Wars database in MS Access. What? You want to see my entity-relationship diagram so far? Sure, why not:
And, once sabbatical hits this summer, I’ll be appealing to y’all (just got back from Texas) to help me fill in the details, to share our knowledge of early modern European warfare with the world.
