Learn how model terrain with r.earthworks. With this tool you can generate new terrain or modify existing terrain using cut and fill operations inspired by earthworking. The first tutorial on the basics of terrain modeling introduces key concepts such as cut and fill operations. The subsequent tutorials introduce more advanced concepts such as relative operations and growth and decay functions. These tutorials demonstrate how to generate terrain, model natural landforms, and model anthropogenic landforms - i.e. earthworks - such as roads, dams, and levees. Read our paper to learn more.
