Dr. @Iza_Karsznia presented our abstract today on "human vs. AI". Can people (even experts) tell if a map is generalized* by AI? Seemingly they can't -- we'll share more soon :)
*Cartographic generalization (en.wikipedia.org/wiki/Cartog…) is highly complex with qualitative decisions.

I noticed that we (@iza_golebiowska and I) tend to publish papers with fancy titles. We had "rainbow dash" and "legends of the dashboard", now the "middle earth" paper is out too tandfonline.com/doi/full/10.… (open access). The question arises: Is the equator not the true middle?
