This paper describes an overall process of procedural generation of natural environments through terrain generation, texturing and scattering of terrain cover. Although described process can be used to create various types of environments, focus of this paper has been put on Mediterranean which is somewhat specific and has not yet received any attention in scientific papers. We present a novel technique for procedural texturing and scattering of terrain cover based on cascading input parameters. Input parameters can be used to scatter vegetation simply by slope and height of the terrain, but they can also be easily extended and combined to use more advanced parameters such as wind maps, moisture maps, per plant distribution maps etc. Additionally, we present a method for using a satellite image as an input parameter. Comparing results with real-life images shows that our approach can create plausible, visually appealing landscapes.
