Here's some examples;
The Forgotten Realms Atlas Project: Book One contains a great high quality map of Silverymoon but m not sure if I can use it on the wiki. I've included an image of the inside cover of the PDF to clarify the licence.
Sundered Realms Player's Guide This short PDF has lots of interesting information about Anchôromé but like a lot of the DMSGuild work it has a bit of a fan-made feel to it.
Any advice would be much appreciated.
