The official Gimp documentation:
Patterns

You will find all kinds of pattern-generating scripts here. Generally, they are quite useful because you can add many arguments to your own patterns.

We'll take a look at the Land script. In this script you have to set the image/pattern size, and specify what levels of random to use for your land creation. The colors used to generate the land map are taken from the currently selected gradient in the gradient editor. You must also supply values for the level of detail, land and sea height/depth and the scale. Scale refers to the scale of your map, just as in an ordinary road map, 1:10 will be typed as 10.
