So when you're done surveying, you take all this data and you punch it into a computer and you find someone that can draw really well, and you have them draft up a map that looks something like this, and it'll show you both a bird's-eye view of the passage as well as a profile view of the passage, kind of like an ant farm view.
Po zebraniu danych wprowadzasz je do komputera i szukasz kogoś, kto potrafi  naprawdę dobrze rysować. Prosisz o szkic takiej mapy, który wygląda mniej więcej tak: pokazuje korytarz zarówno z lotu ptaka, jak i z profilu. Trochę jak ferma mrówek.
