More or less. You wouldn't expect the same level of detail about the shops in town, which you shouldn't really have at the start of the game either unless it's justified by your starting scenario.
It should be a physical item in your inventory, which seems to have already been done with road maps. It's just a case of making it default or at least a option. Having said that, as starting scenarios expand beyond the evac center (where you might be lost), having a array of lootable maps focusing on different areas (city maps, tour guides, nature trails) would be interesting.
Come to think of it, now that z-levels are being added, elevation could be a useful addition to the map. Inb4 kevin tells me i have no clue.
