Still another artist who uses maps as raw materials: Scot J. Wittman. He explains how:

I made large facial portraits of these explorers by collaging together tonal variations of the maps of the areas they explored. I then constructed images of important skulls (e.g. Homo habilis) by using maps of sites in which they were discovered. The next series, kings and queens represented by the areas they ruled, were equally didactic … but had no sense of wonder.
