 Historic examples include maps of buildings and land ownership in the Old Babylonian dynasty more than 3000 years ago and Ptolemy's world map in his masterpiece *Geography* nearly 2000 years ago [@talbert_ancient_2014].
 
 Map making has historically been an activity undertaken only by, or on behalf of, the elite.

 Maps are also often the best way to present the findings of geocomputational research in a way that is accessible.
 Map making is therefore a critical part of geocomputation\index{geocomputation} and its emphasis not only on describing, but also *changing* the world.
