I really, really hate to be all gloom on my first post here at this great site, but I needed a give a word of warning to a mentioned site.
The site Star Wars Deck plans Alliance:
Is fairly hostile towards people using any of their work and very rarely if at all allow folks to use any of their work on anything.
(I could point to many sites who have had problems with them).
I would urge caution against using anything from there other then inspiration.
The folks at Star wars design alliance:
Have been very easy going and quite helpful to fans in general.
I have the entire collection of the Old West End games D6 version of the Star Wars RPG if you'd like I could send you some of their maps (no building tile type maps from them I'm sorry to say) and see if there is anything of interest to you.
Not sure posting those pics here itself is kosher so I will refrain from doing so.
