If you have been around for the thriving years of the #gischat and NACIS1 community on Twitter2, you may remember Joshua Stevens’s post on how to make bivariate maps. Now, eleven years later, Joshua reflects back on it and shares some interesting updates:
Back then, making bivariate maps meant blending color schemes in graphics programs, hand-tuning the corner where both variables run high, and stitching two classifications together into a single attribute your software could understand. It worked in any tool, but it took some patience. A lot has changed since then.
The post looks at updates to software, workflows, and colour spaces, among other things. It is an interesting short read for those interested in cartography or more broadly in the evolution of geospatial technology and technique.

Or you may have come across it in other ways as well, of course. It was very widely shared back then, in my perception.↩︎
