Graphical modeler is a wxGUI extension which allows the user to create, edit, and manage models. It's available from the menu

File → Graphical modeler

Graphical modeler comes with GRASS 6.4.2+.

Note: the tool is currently under development and distributed as experimental prototype. See also wiki page for developers.

The modeler currently allows to:

  • define actions (GRASS commands)
  • define data items (raster, vector, 3D raster)
  • define relations between data and action items
  • define loops (series), conditions
  • validate model
  • run model
  • store model settings to the file (GRASS Model File|*.gxm)
  • export model settings to Python script
  • export model to image
