Stellar cartography was a field of astronomy dedicated to collecting and analyzing data in order to make maps of star systems, planets, and other astronomical objects. One who specialized in this science was known as a stellar cartographer.
After posing as stellar cartographers in September 2152, the three Takret deserters Rellus Tagrim, Renth, and Guri had to admit that they have no knowledge of stellar cartography after being exposed by Doctor Phlox. (ENT: "The Catwalk")
In 2379, the Soong-type android B-4, while under the direction of Shinzon, accessed several unrestricted programs aboard the USS Enterprise-E including "basic stellar cartography, star charts, communications protocols, [and] uplinks from colony tracking stations." (Star Trek Nemesis)
