wxGUI Graphical Modeler

DESCRIPTION

       The  Graphical  Modeler  is  a  wxGUI component which allows the user to create, edit, and
       manage complex models using easy-to-use interface. When performing  analytical  operations
       in  GRASS,  the  operations  are  not  isolated,  but part of a chain of operations. Using
       Graphical Modeler, that chain of processes (ie. GRASS modules) can  be  wrapped  into  one
       process  (ie.  model).  So  it’s easier to execute the model later with slightly different
       inputs or parameters.

       The modeler can be launched from the Layer Manager menu File -> Graphical modeler or  from
       the main toolbar . It’s also available as stand-alone module g.gui.gmodeler.

       The Graphical Modeler allows you to:

           •   define data items (raster, vector, 3D raster maps)

           •   define actions (GRASS commands)

           •   define relations between data and action items

           •   define loops (eg. map series) and conditions (if-else statements)

           •   define model variables

           •   parameterize GRASS commands

           •   define intermediate data

           •   validate and run model

           •   store model properties to the file (GRASS Model File|*.gxm)

           •   export model to Python script

           •   export model to image file
