4. Online Sources Of Maps
From: Bryan Ray (via GMMastery Yahoo Group)
The Dundjinni User Creations forums are a very good source of objects.
RPGMapShare has hundreds of maps of varying quality. And even more objects to populate those maps.
The GM's Apprentice is the host of a massive, organized art collection called the CSUAC. I don't know what that acronym stands for, but it's almost 700 MB worth of art, free of charge.
And, the Cartographers' Guild, where most of the mapmakers are very free to share their work with GMs in need of a good map. Also note that there is a map requests forum there, in case you need something specific and don't mind either waiting a while or paying for it.
