Until Elrey Jeppesen started doing his own maps while flying for VARNEY SPEEDLINES, not much beyond survey charts and they were mostly topographical, there really weren't many reliable road maps for drivers in the 20's either. A part of the Air Commerce Act provided for having the names of towns and cities painted on the roofs of buildings, barns, or water towers (by civic minded volunteers). Jepps charts became popular with his fellow pilots who began copying them for their own usage, soon he was doing more chart reproduction than flying and started doing the pilots bible volumes full time. Now, with the advent of the 787, all charts for everywhere an airplane can fly to or from are installed in the 87's nav system and are updated instantly by satellite so as long as the captain can massage an iPad, he can get the latest 'plate' for wherever he's going.
