QGIS SWMM Conduits Assign Node Fields

Introduction

This tool gives users the ability to reliably and efficiently assign the 'To Node' and 'From Node' fields of a conduits layer. It identifies the nodes snapped to the endpoints of conduits and assigns the 'To Node' and 'From Node' appropriately.
This tool supports in-place editing if selected in the QGIS processing window.

Usage

This tool, Conduits - Assign node fields, can be found in the QGIS processing toolbox panel under TUFLOW >> SWMM. To open the Processing Toolbox panel, navigate to 'Processing' in the menubar and select 'Toolbox'.

Parameters

1. Input Layer: The existing conduits layer that will be assigned the 'To Node' and 'From Node' fields. To only update the fields of some of the layers' features, select the desired ones and tick on 'Selected features only'.
2. Selected features only: If channel(s) in the conduits layer have been selected using the 'Select Features' tool, this option will become available. If this is checked on, the tool will only assign the 'To Node' and 'From Node' fields to the channels that have been selected.
3. SWMM Node Layers: The existing node layers that are snapped to the endpoints of the conduits.
4. Conduits: Determines the location and filename of the output conduits layer.

Note: If 'Edit Feature In-Place' is selected, the tool only requires the 'SWMM Node Layers' parameter. Ie. The tool will override the existing conduits file with the updated 'To Node' and 'From Node' fields.
