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

Creating simple model

Define intermediate data

Model parametrization

Define variables

Start model with data item

Creating simple model in wxGUI Graphical Modeler

Start model with data, define relation manually

Creating model with series (loop) - static list of maps

Creating model with series (loop) - dynamic list of maps

Creating model which exports all GRASS vector maps from given mapset to PostGIS database

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
