Line 1: The '''<u>[[1D_Integrity_Tool_-_Snapping_Tool\|Snapping Tool]]]</u>''' 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.<br> [[File:Snapping tool.png]]<br> Line 12: <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.<br> [[File:Snap options.png]]<br> Line 22: </ol> Please return to the ~~1D Integrity tutorial~~ '''<u>[[1D_Integrity_Tool_-_Tutorial#~~1D_Integrity_Tool~~Using_the_1D_Integrity_Tool\|1D Integrity tutorial page]]</u>''' to continue the tutorial.
