Questions about maps

[Fazer]

Thanks for the info. A broader follow-up ... I've played old-school D&D since the early 80s and am looking for the best way to try out a D&D-style GURPS game. It seems there are three routes I can take:

Am I right in concluding that DFRPG (boxed set) is strictly dungeon crawling but gives you everything you need; the separate line of DF materials is mostly dungeon crawling but adds other aspects such as Taverns, Wilderness Adventures, settings such as Caverntown, etc. and requires a little more work; and the source books such as Fantasy, Magic, etc. are more of a set of guidelines where you need to create the campaign/game world yourself?

Is it possible to start with DFRPG to see if I like it and transition to DF or even Fantasy/Magic source books later to expand the campaign into more of a full-fledged game world? I know a few of the rules are different in DFRPG, but from what I've read it seems like these differences are minor (especially considering that DFRPG uses some of the same books from DF). I know there's a whole game world, Nordland, for DFRPG but it's Viking-themed and I don't think I want that type of campaign.
