Abstract

This paper discusses scripting techniques within the context of GRASS GIS. After an overview over scripting for interactive GRASS sessions, it is shown how GRASS GIS-provided functionality can be used for external applications. This approach of external scripting allows for the application of GRASS GIS-based functionality to be used for standalone applications and embedding in larger automated workflows.
