* Open the attribute table. 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.▼
3. Open the GIS layer <b>1d_x1d_FMT_M01_nodes_001_P.shp</b> within QGIS.

In recent versions of Flood Modeller, it is possible to export the nodes to a TUFLOW Shapefile. This can then be used as the 1d_X1D layer. It should however be noted that the model should be correctly georeferenced within Flood Modeller which isn't always the case. The georeferencing of a model network can be a time-consuming process and should be considered at the project outset.
