Unit 08 - Modeler

Graphic Modeler allows creating, editing, and managing complex models in easy-to-use graphical user interface. Using Graphical Modeler, that chain of processes (ie. GRASS modules) can be wrapped into one process (model). The model can be executed repeatedly with slightly different inputs or parameters.

Our first model will be simple as much as possible based on Unit 05 - Perform computation. Actually the model will perform two operations:

  1. set mask based on vector cloud mask file (r.mask) and
  2. compute NDVI (i.vi)

Graphical Modeler can be launched from menu File ‣ Graphical modeler or by grass-modeler-main Graphical Modeler from main toolbar (or alternatively as g.gui.gmodeler module from console).
