When I personally started with OpenSimulator I spend what seemed an eternity searching the web for RAW terrain files I could use to make my new region look something a little more like I wanted. The only choices I found were for use on SecondLife and payable in L$. So I decided to start making some available for OpenSim users (although they should be compatible with SL too).

In the spirit of OpenSource and OpenSim I have made these avaliable free of charge below. Please use them responsibly, this resource is for everyone at no cost please do not resell my RAW files.
