<li> Open the <b>FloodModeller_Nodes_P.shp</b> layer from Module_Data\Module_01\gis folder.</li>
<li> Save as <b>1d_x1d_FMT_M01_nodes_001_P.shp</b> within the FMT_tutorial\FMT_M01\TUFLOW\model\gis folder. </li>
<li> Open the GIS layer <b>1d_x1d_FMT_M01_nodes_001_P.shp</b> within QGIS.</li>
<li> Interrogate one of the digitised points and inspect the attributes. This layer only has a single attribute correlating to the unique name of a RIVER, INTERPOLATE or REPLICATE unit within the Flood Modeller model. Note that the node IDs are case-sensitive as this is a requirement of Flood Modeller. At junctions, both the upstream and downstream nodes must be digitised within this layer.</li>

<li> Save the file.

<p> For real-world models, this GIS layer may be largely automated provided the original Flood Modeller model is geo-referenced. Within Flood Modeller it is possible to output a text file containing each of the model nodes along with their Eastings and Northings. This text file can then be brought into any GIS package and used to create the points within the GIS layer to be used by TUFLOW.</p>
</div>
You have now created the GIS layer representing the Flood Modeller nodes for reading into TUFLOW. Return to the [[Flood_Modeller_Tutorial_Module01#Define_the_1D.2F2D_Boundary_Links|Flood Modeller Tutorial Model]].
