I love old maps on weekends; by day, I love modern spatial datasets at the large earth-science agency at which I work (OK, it's a part of the Dept. of Injustice as referenced in a recent/. article on the 100% M$ solution. My team is about 50% Mac, 40% Win, 10% *nix - but that's OT).
Maps can be considered a superset of the relational/OO database; x, y, z and t have special properties (try indexing on x and y).
If you'd like to learn more of this facinating topic, do the usual searches but be sure to include GIS (geographic information system, not guessing is simpler, as some have suggested).
