In this page we describe the GIS modifications required for tutorial module 5 using ArcGIS or QGIS.
=Method=
<ol>
<li>From the '''model\gis\empty\''' folder copy the '''2d_zsh_empty_R.shp''' into the '''model\gis\''' folder named as '''2d_zsh_M05_development_001_R'''.</li>
<li>Add this layer to the map window and make this the editable layer.</li>
<li>Open the '''Fill_Area''' and '''Cut_Area''' layers provided in the '''Module_Data\Module_05\'''.</li>
<li>Copy the polygon from the '''Fill_Area''' table and paste this into the '''gis\2d_zsh_M05_development_001_R''' layer.</li>
<li>Set the following attributes:<br>
{| align="center" class="wikitable" width="50%"

! style="background-color:#005581; font-weight:bold; color:white;"| Attribute
! style="background-color:#005581; font-weight:bold; color:white;" width=50%| Value
|-
| Z || 50
|-
| dz || 0
|-
| Shape_Width || 0
|-
| Shape_Options || MAX NO MERGE
|}
The attributes are described fully in Table 4.8 of the 2010 TUFLOW manual. However, in brief we are setting the elevation to 50 m (Z = 50), where the elevation of 50 m is above the current surface elevation ("MAX") and the "NO MERGE" option indicates that we do not want to merge the elevations at the perimeter of the polygon. Essentially, within the fill polygon we are stamping the elevation of 50 m into the model where the elevation is currently less than 50 m.</li>
<li>Copy the polygon from the '''Cut_Area''' table and paste this into the '''gis\2d_zsh_M05_development_001_R''' layer.</li>
<li>Set the following attributes:<br>
{| align="center" class="wikitable" width="50%"

! style="background-color:#005581; font-weight:bold; color:white;"| Attribute
! style="background-color:#005581; font-weight:bold; color:white;" width=50%| Value
|-
| Z || -1
|-
| dz || 0
|-
| Shape_Width || 0
|-
| Shape_Options || ADD NO MERGE
|}
For this polygon we are adding -1 to all elevations within the polygon, i.e. within the polygon we are subtracting 1 m from all the elevations.</li>
<li>Save the table and export the 2d_zsh layer so that it is ready for use in TUFLOW.

</ol>
=Conclusion=
The GIS dataset has been created. The next step is to modify the control files. [[Tutorial_Module05_Archive#Control_File | Please return to the module 5 page]].
