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

See also manual page.

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

Python editor in wxGUI Graphical Modeler

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 }}
