FM Tute M01 ARC x1D Nodes

Introduction

We will now create TUFLOW GIS layers to reference the nodes within the Flood Modeller model.
These node layers are the primary way that TUFLOW references the Flood Modeller sections.

Method

1. Open the FloodModeller_Nodes.shp layer from Module_Data\Module_01\shp folder.
2. Save as 1d_x1d_FMT_M01_nodes_001_P.shp within the TUFLOW\model\gis folder.
3. Open the GIS layer 1d_x1d_FMT_M01_nodes_001_P.shp within ArcGIS.
4. Interrogate one of the digitised points and inspect the attributes. Note that each point has a unique name which correlates to a RIVER, INTERPOLATE or REPLICATE unit within the Flood Modeller model. At junctions, both the upstream and downstream nodes must be digitised within this layer.

5. Save the file.

   Key Tip!

   The node IDs are case-sensitive as this is a requirement of Flood Modeller.
