Simulated with Exoplasim. Map created with Koppenpasta, Imagemagick, Freds "emboss" script and sometimes also Krita. Used Scotese 1deg Paleodem to make Exoplasim simulation and 6min PaleoDEM to visualize. Operating system Ubuntu etc. to run script.

"lang.png" and "sea.png" uses scaling factor 25, that produces 1600x800 map
"koppen.png" uses scaling factor 1
