A far-from-comprehensive list of useful sites where you can find mapping assets that you can use in MapForge, via drag-and-drop.
This is a work in progress. Expect more links to be added over time.
Assume that all art is for personal use only, unless commercial use is specifically mentioned/allowed.
(the site itself has seen better days, as some postings never survived a migration of the back-end software, but the artwork is generally great)
Link to MapForge-specific subforum (post things here, people! This is where MapForge users will share their art with the rest of the MapForge community)
The Vintyri Project

(Make sure that purchased art is available as downloadable PNGs)
Fantasy Mapping Art
A hoard of PNGs that I believe someone collected from the Dundjinni User Forums and put into a single 384 MB Zip file. As far as I know, that’s all legit “pubic domain” content, since I’m not seeing anything from commercially-sold art packs. Much of the CSUAC content is in there, too, for those who don’t already have a copy of the CSUAC archives.
