HITW Terrain Textures
This is a full set of land textures specially created for use in game development, simulation scenery generation, real-time graphics environments, geotypical landscape design, and other projects that require fantastic looking ground cover. They are especially useful for flight simulations.
Each texture plate in the set is created with full seamless tiling capability, and all textures are designed to mesh effortlessly with one another for a totally natural, eye-catching look. The resolution represented is 15 meters per pixel.
We originally created these textures in 2003. The entire set is now available for free commercial or non-commercial use in your own games and projects, as long as credit is given (see CC License).

Comments
I note the source https://howintheworld.com/textures/ , description here and the licence text file in the download says CC BY 4.0, but the OGA licence is CC BY 3.0 - should 4.0 be added or set instead?
Thanks for the heads-up. I just revised it.
