I am in the midst of creating the signpost feature class and table. I am inputting each of the edge elements into the non-spatial signpost table. In the future, as I update my street network using the newest County Street Centerline Data, is there a way for me to update those edge attributes? Or am I simply going to be stuck re-editing all of the edge data in that table? I couldn't find any information on it. I know that I can update by geometry on my turns feature class, but that is because it is a spatial table with all of the information necessary and the appropriate geometry associated with it. Please let me know if anyone else has had similar problems and/or a possible solution. Thanks!
