<li>Import in an empty <b>2d_bc_empty_P.shp</b> layer from within the FMT_tutorial\FMT_M01\TUFLOW\model\gis\empty folder.</li>
<li>Save the layer as <b>2d_bc_hxi_FMT_001_P2d_bc_FMT_M01_HX_001_P.shp</b> in the FMT_tutorial\FMT_M01\TUFLOW\model\gis folder. </li>
<li>Open the <b>1D_2D_Points.shp</b> GIS layer from Module_Data\Module_01\gis folder. Select all objects from within this layer, copy and paste into <b>2d_bc_hxi_FMT_001_P.shp2d_bc_FMT_M01_HX_001_P</b>. </li>
<li>Interrogate one of the digitised points and inspect the attributes. The ‘type’ attribute is ‘ZP’ to denote that it is a z-point. The ‘f’ attribute is the elevation of the bank link in mAOD. </li>
<li>Now add the layer <b>2d_bc_FMT_M01_HX_001_L.SHP</b> from the '''FMT_tutorial\FMT_M01\TUFLOW\model\gis''' folder created in the previous step. Note that all the 'ZP' points created in the layer <b>2d_bc_FMT_HX_001_P.SHP</b> are snapped to vertices of the layer <b>2d_bc_FMT_M01_HX_001_L.SHP</b>. This is because these two layers work together to define the bank locations and crest elevations. The layer <b>2d_bc_FMT_M01_HX_001_L.SHP</b> defines the location and the layer <b>2d_bc_FMT_HX_001_P.SHP2d_bc_FMT_M01_HX_001_P</b> defines the elevations.
