Upstream / Downstream Network Trace

The Upstream Network Trace and Downstream Network Trace tools allow you to trace from any node or link in the network to the upstream / downstream extents of the network. The trace assumes that the network connectivity (pipe direction) is correct. The tool simply traces all possible upstream / downstream paths from the selected starting point. If the trace stops before reaching the extent of the network, then:

To carry out a trace:

  1. Click on the (for upstream trace) on the More GeoPlan Tools Toolbar or the (for downstream trace) button on the GeoPlan Tools Toolbar, or select Tracing tools | Downstream trace mode or Tracing tools | Upstream trace mode from the GeoPlan menu.
  2. Click on any node or link. If there is more than possible path from a node, you will be asked choose which link you want to trace the extends of.

Alternatively, select a link or, for SWMM networks only, a node on the GeoPlan, right-click to display the context menu, and then select the Trace upstream or Trace downstream option from the selected object's menu choices.

Tip

When using a trace tool, you can carry out a trace in the opposite direction by clicking the button and then holding down the ctrl key while clicking on a node or link. For example, the combination of the upstream trace tool and the CTRL key will result in a downstream trace being performed.
