=Method=
<li>Import
<li>Open the <b>1D_2D_Points_P.shp</b> GIS layer from '''Module_Data\Module_01\gis''' folder. Select all objects from within this layer, copy and paste into the <b>2d_bc_FMT_M01_HX_001_P </b> layer. </li>▼
▲<li>Open the <b>1D_2D_Points_P.shp</b> GIS layer from Module_Data\Module_01\gis folder. Select all objects from within this layer, copy and paste into the <b>2d_bc_FMT_M01_HX_001_P </b> layer. </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 which will define the elevation on the banks. 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 </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_M01_HX_001_P</b> are snapped to vertices of the layer <b>2d_bc_FMT_M01_HX_001_L</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 </b> defines the location and the layer <b>2d_bc_FMT_HX_001_P </b> defines the elevations.
