View source for Tute SAGA M01 Create Projection

<ol>
=Introduction=
This page describes the process of creating a new "Shapes" layer in SAGA.  We will define the projection of this table. It will be used to set the GIS coordinate system (projection) of the TUFLOW model.

=Method=
<ol>
<li> Using the drop menus navigate to ''Modules >> Shapes >> Construction >> Create New Shapes Layer''.
[[File:Tute M01 Saga New Shape.png|frame|none|Create a new Shapes Layer]]
<li> Set the ''Name'' field to '''Projection'''. Leave the remaining options as the defaults.

A new shape layer called '''Projection''' should have been created, this should be visible in the Data tab of the workspace.

The next step is to define the projection of this shapefile.
<li> In the menus select ''Modules >> Projection >> Set Coordinate Reference System''.
<li> In the dialogue set the following:<br>
*Geographic Coordinate System to WGS84
* Projected Coordinate Systems to WGS84 / UTM Zone 60S
* Under Shapes add the Projection shape (this applies the setting to this shape layer).
* Select ''Okay''<br>

<li> Right click on the Projection layer in the Data tab of the workspace and select ''Save As''.<br>
<li> Save the file under the '''TUFLOW\Model\gis\''' directory as '''Projection.shp'''.
</ol>

=Conclusion=
A new GIS layer has been created and this will be used to define the projection of the TUFLOW model. Please return to the tutorial module page <u>[[Tutorial_Module01#Set_GIS_Projection_and_Create_Empty_.28Template.29_Files | here]]</u>.
