I'm starting this thread because some people have favorite types of cartography. mine is interstellar navigation cartography. as well as mapping alien planets. ive divided the milkyway galaxy into 4 quadrants each with 24 sectors alpha through omega 48 subsectors in each sector, in total there are 4 quadrants, 96 sectors, & 1152 Subsectors in our galaxy alone. Earth: quadrant Alpha/sector Alpha/subsector 1Alpha. so what Cartography interests you.
