I guess it may fit your workflows, so please read a bit about them here if you've never heard of them, maybe it's what you need.</SPAN><BR /><BR /><A href="http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/What_are_geometric_networks/002r00000001000000/">http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/What_are_geometric_networks/002r00000001000000/</A><BR /><BR /><SPAN>To get a comparison of geometric networks and network datasets (i.e., Network Analyst), refer to this nice podcast script:</SPAN><BR /><A href="http://www.esri.com/news/podcasts/transcripts/arcgisnetworkanalyst_networksandnetworkmodels.pdf">http://www.esri.com/news/podcasts/transcripts/arcgisnetworkanalyst_networksandnetworkmodels.pdf</A></BODY></HTML> Thu, 16 Feb 2012 15:27:05 GMT https://community.esri.com/t5/arcgis-network-analyst-questions/sewershed-delineation/m-p/105938#M1038 AlexeyTereshenkov 2012-02-16T15:27:05Z
