Thanks to all who responded about my topology inquiry. I really appreciate all of your responses. I received several suggestions such as MapLogix, "FixGapsAndOverlaps", SpatialWare's Topology Manager, and several built in cleaning functions in the newer SpatialWare versions. Thanks again for your time and much valued help. ---------------------------------------------------------------------- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
