Probably the best resource is the levels page at
https://pkmx.github.io/wzi-levels/ . Maps are linked from there. A guide might explain how to use this for complete newbies, but it's really well laid out. Thanks pkmx!
In the git repository for that page there's a csv file (data.csv) that can be imported in a spreadsheet that lists almost everything in a level. I think that's what you are talking about.
Probably the only information not in that file which I have missed at times are particular mine locations in later levels when a tech advance needs something smelted. Not a huge deal.
There are previous forum threads in pathways for Hex Earth and Plateau I believe, though of course these SA levels are not for beginners!
