An add-on tool for computational terrain modeling in GRASS. This is the repository for development version. The stable release is in the GRASS Addons Repository. To learn more see the paper, documentation, and tutorials.
Install the stable release for GRASS 8.5 and above:
g.extension extension=r.earthworksInstall the development version for GRASS 8.5 and above:
g.extension extension=r.earthworks url=https://github.com/baharmon/r.earthworksFor older versions of GRASS, install r.earthworks-3.1.0. Download and unarchive this version from Zenodo. Then install with g.extension using the full file path to the extracted directory as the url.
curl -L "https://zenodo.org/records/21865092/files/baharmon/r.earthworks-3.1.0.zip?download=1" -O && unzip r.earthworks-3.1.0.zip

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.
