Hanging nodes, arc overshoots and undershoots, extra pseudonodes and unlabled or multi-labeled polygons were corrected as soon as they occurred.  Error searches and corrections also took place once each coverage was complete as well as once they were joined.   This was to continually check whether polygons or labels were missing, to delete unnecessary pseudonodes and to verify and compare the given polygon id’s with the original geological base map.
