The #30DayMapChallenge was initiated by Topi Tjukanov on Twitter. This is open to anyone who would like to show a map, whatever the software is. In this blog post, I will show maps made with R. I add constraints to myself for fun. This week, I will create maps that remind map makers that Earth is …

Spatial interpolation on Earth as a 3D sphere
Earth map is usually presented flat. Geographical coordinates usually go from -180° to +180°. Spatial interpolations using coordinates may be tricky as -180° is equal to +180°. Here I propose a way to realize spatial interpolations on Earth as a sphere and then map the outputs in 3D using rgl. The …
