Also, you mentioning topographic maps makes me giggle and think of this exchange from "Easy Money":

[Cut to Fraser and RayK. Dief is waiting for them at the entrance to the Power Building]
RayK: How'd he beat us?
Fraser: Well, he must have taken a short cut.
RayK: He knows short cuts?
Fraser: Well he does study maps.
RayK: What kind of maps?
Fraser: Road maps, street maps, topographic maps.
