Have been working with the ESRI's Data Reviewer Extension to identify unnecessary nodes. The "Unnecessary Nodes Check Properties" dialog implies that the result return (1) a node (if topology exists) or (2) a polyline (info topology exists). I can't seem to get the dialog to return nodes only polylines and I have a topology built. Any suggestions?
To obtain the nodes rather than the polylines one must first create a geodatabase topology for the features in questions. Then using the Data Reviewer tool bar create a "Reviewer Session" using the "Reviewer Session Manager." Simply browse to a Geodatabase (e.g. Scratch.mdb) and then click New to create session. Once a session has been created the appropriate checks (e.g. Unnecessary Node Checks) can be set up and then run by clicking the "Feature to Validate) and then selecting "Write to Reviewer Table."
