== Introduction ==
This page details the method for using QGIS to set an active model area. A preliminary model extent is provided for the tutorial model, this will be copied into a TUFLOW format file.

== Method ==
<ol>
<li>Load the '''2d_code_empty_R.shp''' template file from the '''TUFLOW\model\gis\empty''' folder.
<li>Right click on the empty (template) layer '''2d_code_empty_R''' in the layer control and select '''Save As...''' 
[[File:Tute M01 QGIS 2d code1.png | frame | none]]
 
<li>In the '''Save As''' section, hit the '''Browse''' button and save the file in the '''TUFLOW\model\gis\''' directory as '''2d_code_M01_002_R.shp''' 
[[File:Tute M01 QGIS 2d code2.png | frame | none]]
<li>Open the newly saved '''2d_code_M01_002_R.shp''' file.
<li>The empty file can now be closed, to do this right click on the layer in the '''Layers''' section and select remove. 
[[File:Tute M01 QGIS 2d code3.png | frame | none]]
<li>Load the '''Boundary_region.shp''' file from the '''Module_Data\Module_01\QGIS\''' folder.
<li>Set the '''2d_code_M01_002_R''' layer as editable, by right-clicking on the layer and selecting '''Toggle Editing'''. 
[[File:Tute M01 QGIS 2d code4.png | frame | none]]
<li>Select the polygon provided from the '''Boundary_region''' layer. To do this, select the layer in the Layer control section, and hit the '''Select Single Feature''' from the menu as shown in the image below. Once this is selected, highlight the polygon (it should change colour when selected). 
[[File:Tute M01 QGIS 2d code5.png | frame | none]]
<li>Select ''Edit >> Copy Feature'' (Control + C).
<li>Select the '''2d_code_M01_002_R''' layer in the layer control and select ''Edit >> Paste Feature'' (Control + V).
<li>Select the ''Identify Feature'' button (arrow beside blue i icon), and click on the polygon in the Map Window. The information window should show that the Code Feature is set to 1. This is shown in the image below.
:'''Note:''' If this is not the case, expand the ''Actions'' item and select ''Edit Feature Form''. 
[[File:Tute M01 QGIS 2d code6.png | frame | none]]
<li>To finish the edit, select the toggle editing and when prompted, save the file.
<li>Enter the following line of text into the TGC file '''after''' the <tt>Set Code </tt> <tt>== 0</tt> command and save the TGC file. 
<tt>Read GIS Code </tt> <tt>==</tt><tt> ..\model\gis\2d_code_M01_002_R.SHP</tt> 
</ol>

== Conclusion ==
QGIS has been used to create a 2d_code layer which sets the code value for cells inside the boundary polygon to active (code = 1). Please return to the tutorial model module 1 page [[Module1_test_Archive#Discussion_on_Command_Order|here]].
