Portions of several planets have been drawn/mapped in some of the "Inside the Worlds of Star Wars Episode 1". (those big Cross Section books) For instance, Naboo has an axonometric, there's a large scale Mos Espa, and a more detailed flat map of the pod race course. And there are a bunch of other maps at a town scale level.

http://www.starwars.com/vault/databank/ Has written descriptions (canon, EU & filmed location) information. So that might provide the overall list of places classified.

The Gaming guides might have full maps:
