Graphical modeler is a GUI application which allows the user to create, edit, and manage models interactively.

The Graphical Modeler is available in GRASS 6.4.2+ from the Layer Manager menu File → Graphical modeler or from the toolbar File:Modeler.png.

In GRASS 7 the tool is also available from the command line (g.gui.gmodeler).

See also manual page and wiki page for development issues.

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

Creating model which exports all GRASS vector maps from given mapset to PostGIS database (including schema)

1) create schema with name of input mapset

2) copy vector maps from selected mapset to the current and stores their attributes in SQLite database

3) exports GRASS vector maps to the selected PostGIS database
