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
