Is there any calculation to be done here? What constitutes a node type?
I think we can do this simply:
nodetype
attribute at each nodeNode Types: -river to river -braid to non-braid -braid to braid -outflow (most downstream point in network (does this need further definition?) -headwater -mainstem to tributary (I'm not sure we need this)
Nodes will need to have more than one node type
Made some progress here. I created a new experimental script demonstrating how to identify and tag stream reaches by "reach_type". This would be the first step in identifying node types.

This is great. If I'm reading correctly though do we require an attribute of TYPE_ATTRB
?
Where does this come from? How pervasive is it in CHaMP Shapefiles or do we have to generate it somehow?
TYPE_ATTRB
is just the name of the new "ReachType" attribute field that will store the reach type variables. I figured it won't be something that will be changed by the user, which is why I made it a constant.
Identify different node types within the network.
