New page

The snapping tool checks that all input 1D network lines (channels) and 1D network points are correctly snapped. For lines, it will check that both the upstream and downstream end of the line is snapped to the upstream or downstream end of another line. For points, it will check that each point is snapped to either an upstream or downstream end of a line.
This tool also has an option to automate snapping correction and will find the closest connection within the radius and snap them together for both lines and points.
Snapping is probably the source of 95% of TUFLOW pre-processing errors so it is highly recommended that the snapping is check prior to being added a network to TUFLOW.
<ol>
<li> Ensure that '''1d_nwk_MI01_Pipes_001_L_EG1_ID1''' is referenced in the 1D network Line Layers and select the Snapping tab.
<li> Select the option to ‘Use an exclusion radius when checking for snapping’ and set the exclusion radius to ‘1’. Run the tool. The ‘Exclusion Radius’ will not flag snapping errors for lines if the nearest line end is outside the exclusion radius. 
[[File:Snapping tool.png]] 

An output layer will again be generated, highlighting a number of locations where the snapping check has failed. Zoom in to either of the highlighted locations and you will see some pipes which are not correctly snapped.

<li> Add the 1d_nwk_MI01_Pits_001_P.shp file to the ‘Input Network Points’ section of the 1D integrity tool. This will enable us to ensure points and lines are both snapped together.
<li> Rerun the snapping tools but on this occasion select the option to ‘Auto-Snap’. Set the ‘Search Radius’ to 1m. 

[[File:Snap options.png]] 

This will generate two new layers called '''1d_nwk_pipe_integrity_L_workshop_EG1_ID1_SN1''' and '''1d_nwk_pit_integrity_L_workshop_SN1''' which are correctly snapped as shown below.
<li> Locate the pipes identified in step 2. You should now see that they are snapped together which will ensure continuity and avoid errors when running the TUFLOW simulation.
