Carbon footprint through time, II
Map using Equal Earth not Web Mercator projection
In saying Map using proportional not choropleth symbology, my previous post showed a more appropriate way to convey CO2 emission without the distraction of country sizes that vary a lot.
But as Kenneth Field pointed out recently: Mercator, it’s not hip to be square. I found Equal Earth projection by @bojansavric and @MtnMapper very satisfying way to convey global data, such as in my CLIWOC historic tall ships maps and historic wind maps. Notice however those are videos not maps! Why? I couldn’t post them on arcgis.com in that projection… Until now.
Following instructions above to avoid Mercator projections, I did this:
- created a UN Countries map in Equal Earth projection
- published it as a vector tile in that projection (banner picture)
- and simply posted atop it perCapita and TotalCO2 hosted layers
Note 1: my hosted layers all in WGS84 were all posted as Web Mercator
Note 2: perCapita & TotalCO2 are ordered then posted ‘time aware’ using an extra ‘time’ attribute per country in increasing PCsize & TCsize — this is a size NOT a time animation, it’s rather meant to show countries in increasing CO2 output.
The upshot is that maps post in geographically more sensible context… and I don’t have to create videos to show them!
