<h2>NAME</h2>
<em><b>wxGUI.Modeler</b></em>
<h2>DESCRIPTION</h2>
Note: <b>wxGUI Modeler is currently under development. It's provided as
an experimental prototype.</b>
<p>
The <b>Graphical Modeler</b> is
a <em><a href="wxGUI.html">wxGUI</a></em> compoment which allows the
user to create, edit, and manage models. The modeler can be launched
from the menu <tt>File -> Graphical modeler</tt> or by clicking on
icon <img src="icons/modeler-main.png"> in the toolbar.
<p>
The modeler currently allows you to:
<ul>
<li>define data items (raster, vector, 3D raster maps)</li>
<li>define actions (GRASS commands)</li>
<li>define relations between data and action items</li>
<li>define loops (eg. map series) and conditions (if-else statements)</li>
<li>define model variables</li>
<li>parameterize commands</li>
<li>define intermediate data</li>
<li>validate and run model</li>
<li>store model properties to the file (<tt>GRASS Model File|*.gxm</tt>)</li>
<li>export model to Python script</li>
<li>export model to image file</li>
</ul>
