Creating nodes

Tools ››
Parent Previous Next

The nodes of the network are an important component of a river network.  They are the locations where polylines connect to each other.


A polyline is made up of vertices and the end vertices are referred to as nodes.


If you have made any changes to the network, such as deleting or moving polylines you must rebuild the associated node information.


Stream ordering algorithms require the network to have correct node information for it to process correctly.


RivEX allows you to:


Create new node ID fields for the river network

Create a layer of all network nodes

Create a layer of only mouth nodes

Create a layer of only source nodes

Create a layer of only pseudo nodes

Transfer polylines attribute to the nodes layer

Create a new network free of pseudo nodes
